• New user - need tips to improve the performance and graphics ability

  Hello

  I am a new user.  I loaded Windows 7 64-bit today, and it seems to work fine. (I used only Explorer.) I downloaded by Reallusion CrazyTalk and software is lagging terribly, and the image is blurry. The Forum of CrazyTalk, they recommend updating graphics drivers to fix blurry images. On the NVIDIA site, when I asked her to automatically detect the driver update, it says none is available for my computer (my Mac).

  Question: They have updates driver for Windows... When I am running Windows via Fusion, should I different graphics drivers than those on my Mac?  If so, means that I need another graphics card?  * Of course I'm not super technical. **

  I have attached a screenshot of my info/display of charts:

  

  In addition, molten, I increased the RAM to 3 GB (3000 MB), but it has not improved the situation.

  CrazyTalk allows the user to make a photo 'talk '... It is lively and contains the audio.  I usually save files as uncompressed reviews that are about 4 GB in size (when I worked directly on a PC) but today to test it's obviously "too much" for this system.  (It would have probably been about 2 GB). So I recorded a MP4 (3.7 MB), which has always been a time loooooooong to save - 30 minutes.

  Other info:

  Model name: iMac

  Model ID: iMac9, 1

  Processor name: Intel Core 2 Duo

  Processor speed: 3.06 GHz

  Number of processors: 1

  Total number of cores: 2

  Memory: 4 GB

  Bus speed: 1.07 GHz

  Boot ROM version: IM91.008D.B08

  Version of the SCM (System): 1.37f3

  I would appreciate advice and links to information that will help me.

  Thank you

  Welcome to the Fusion community.

  Question: They have updates driver for Windows... When I am running Windows via Fusion, should I different graphics drivers than those on my Mac?  If so, means that I need another graphics card?

  Your don't need another graphics card.  By necessity, VMware can pass through native graphics of your iMac to any guest including Windows operating system.  VMware provides its own graphic adapter of substitute (WDDM 3D) or VMware SVA II, with its own pilots.  Apple takes care to provide you with the latest drivers for OS X, you will never have to download all the drivers directly from the graphics vendors.  Details about the virtual hardware and its differences of capacity are covered in the FAQs on VMware Fusion

  Regarding the VMware graphics drivers who are in the VMware tools and are supported if you have installed Windows 7 using Windows Easy install feature in the new computer Wizard.  If you do not use Windows Easy Install (or don't remember), the icon of blue squares of VMware in the system tray is a Visual indicator, they are installed.  But you can confirm the video adapter by using the Control Panel, search for display > change display settings > advanced settings to look at your graphics card.  For Win7, the default value is VMware SVGA 3D.

  Whenever you want to refresh the VMware drivers you can select Virtual Machine > install VMware Tools to install or run the option repair after the Welcome screen.

  In addition, molten, I increased the RAM to 3 GB (3000 MB), but it has not improved the situation.

  Based on the requirements of CrazyTalk6 system I could find, you do not need to allocate as much RAM (3 GB).  Depending on your other needs Windows 7, 1 GB to 2 GB would be better, based on your host, the RAM size.

  Pentium IV 2 GHz or higher recommended

  512 MB of RAM or more recommended

  1 GB space drive or higher recommended

  Duplex Sound Card/VGA Card/keyboard/mouse/Microphone/Speaker

  Display resolution: 1024 x 768 or higher

  Video memory: 128 MB RAM or higher recommended

  Windows 7 / Vista / XP SP2

  Internet Explorer 6 or higher, Firefox 2 or higher

  DirectX 9 and WMEncoder 9 are required to export WMV

  Recommended hardware:

  CPU dual core or higher recommended

  1 GB of RAM or more recommended

  Hard drive 2 GB or more recommended

  Video memory: 256 MB RAM or higher recommended

  Things to try:

  The 3D Aero interface may impose the virtual graphic adapter, then you could try to disable that by getting the properties of the desktop background, choose Customize and change the theme of Windows 7 Basic.

  More radically, you can stop the virtual machine and disable 3D graphics in the VM > settings > display > uncheck "Accelerate 3D graphics."  This will cause Windows 7 use the legacy VMware SVGA II adapter.  The oldest non - 3D adapter looks like it meets the system requirements but requiring DirectX 9 encoding for WMV exporting.   If you save without video compression, that may be OK.  If the non - 3D adapter does not meet requirements, I am sure that the program will display.

• How to improve the performance of the Intel X 3100 on Satellite L300

  Hello everyone.

  First of all, I don't know if this is an appropriate place to post this thread here or no, but I would like to share with you the experience relating to the improvement of Intel X 3100 (GMA965).

  As we know, there is no driver is good for this chipset from Intel for the moment, especially on VIsta.
  This improvement is made by editing the registry of Intel driver.

  * Steps: *.
  * 1 * open run (Windows + R)
  * 2 * enter Regedit
  * 3 * open the subfolder: * HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\Video\ *.
  * 4 * from there you'll see lots of subfolders in video, open each one until you see the folder * 0000 * with + _3DMark03.exe +.
  (For example, my is {HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\Video\ {B5990899-FBCB-45E1-B0B0 *} and reg DWord _3Dmark03.exe lies in two subfolders * 0000 * and * 0001 *})
  * 5 * in * 0000 * and * 0001 *, create two new * DWORD format: * _software.exe* and * ~ software.exe*, value = 1 (hexadecimal). Here, * software * represents the name of the program you want to accelerate as * _photoshop.exe* and * ~photoshop.exe*
  * 6 * in these files, search for * GFX_Options * and change its value to * 1 *.
  * 7 * restart your computer to activate GFX
  * 8 * repeat step 4 to add more programs you want

  Other updates for the drivers are under developed. However, this method will help you to speed up your computer performance with + heavy + graphical software required. I got double FPS on some software on my Toshiba L300 using this method such as Corel, WarcraftIII and Titan Quest (24-32 fps measurement by Fraps)

  Hope it's useful for everyone.
  Best wishes

  How can I improve the performance of my compaq presario V2000, its very slow!

  According to many things (specifications, you have now installed vs the programs he came originally with programs, etc.)-it may or may not work better that ever he does now.  However, in terms of nothing other than the software and others on the subject - there are some things you can do to optimize performance.

  Search for malware:

  Download, install, execute, update and perform analyses complete system with the two following applications:

  • MalwareBytes (FREE)
  • SuperAntiSpyware (FREE)

  Remove anything they find.  Reboot when necessary.  (You can uninstall one or both when finished.)

  Search online with eSet Online Scanner.

  The less you have to run all the time, most things you want to run will perform:

  Use Autoruns to understand this all starts when your computer's / when you log in.  Look for whatever it is you do not know using Google (or ask here.)  You can hopefully figure out if there are things from when your computer does (or connect) you don't not need and then configure them (through their own built-in mechanisms is the preferred method) so they do not - start using your resources without reason.

  You can download and use Process Explorer to see exactly what is taking your time processor/CPU and memory.  This can help you to identify applications that you might want to consider alternatives for and get rid of all together.

  Do some cleaning and dusting off this hard drive:

  You can free up disk space (will also help get rid of the things that you do not use) through the following steps:

  You can disable hibernation if it is enabled and you do not...

  When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
  -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

  You can control the amount of space your system restore can use...

  1. Click Start, right click my computer and then click Properties.
  2. click on the System Restore tab.
  3. highlight one of your readers (or C: If you only) and click on the button "settings".
  4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
  5. click on OK. Then click OK again.

  You can control the amount of space used may or may not temporary Internet files...

  Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

  -Open a copy of Microsoft Internet Explorer.
  -Select TOOLS - Internet Options.
  -On the general tab in the section 'Temporary Internet files', follow these steps:
  -Click on 'Delete the Cookies' (click OK)
  -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
  -Click OK.
  -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
  -Once it's done, click OK, close Internet Explorer, open Internet Explorer.

  You can use an application that scans your system for the log files and temporary files and use it to get rid of those who:

  While probably not 100% necessary-, it is probably a good idea at this time to ensure that you continue to get the updates you need.  This will help you ensure that your system update is ready to do it for you.

  Download and run the MSRT tool manually:

  Reset.

  and...

  Download the latest version of Windows Update (x 86) agent here:
  http://go.Microsoft.com/fwlink/?LinkId=91237
  ... and save it to the root of your C:\ drive. After you register on the root of the C:\ drive, follow these steps:

  Close all Internet Explorer Windows and other applications.

  AutoScan--> RUN and type:

  Now that your system is generally free of malicious software (assuming you have an AntiVirus application), you've cleaned the "additional applications" that could be running and picking up your precious memory and the processor, you have authorized out of valuable and makes disk space as there are no problems with the drive itself and your Windows Update components are updates and should work fine - it is only only one other thing you pouvez wish to make:

  Get and install the hardware device last drivers for your system hardware/system manufacturers support and/or download web site.

  If you want, come back and let us know a bit more information on your system - particularly the brand / model of the system, you have - and maybe someone here can guide you to the place s x of law to this end.  This isn't 100% necessary - but I'd be willing to bet that you would gain some performance and features in making this part.

• Anyone have information about the software to improve the performance of a computer called "MECHANICAL SYSTEM"

  original title: windows xp

  has anyone information about the software to improve the performance of a computer called "MECHANICAL SYSTEM"?

  It is located on the website at WWW.IOLO.COM.

  Maybe someone of expertise of knowledge about this software?   or maybe someone has experience with this product?

  There is a similar product, without the costs?

  DO NOT BUY OR INSTALL "SYSTEM MECHANIC".

  IT will bog your system with errors, which would mean probably a complete restoration of your system.

  Dell recommends and sells it from their technical support group and SHAME on THEM for DOING SO.

  THIS SOFTWARE IS A TRAGEDY IN THE MAKING.

  Go to PC Mag reviews and you will see for yourself that there is a very LOW RATING and under normal conditions, you need software to mess with your registry.

  I know someone who has installed this program and we always try to fix all of the errors generated by mechanical system.

  We did a complete restoration and stil having problem.

  Thus he PURCHASE a CERTAINLY DO NOT GOLD INSTALLER CE PROGRAM.

  Hi Cynthia,.

  1 have you ever done any hardware or software changes to the PC?

  2. What is the brand and model of the PC?

  3. What is the full error you get when you try to evaluate the computer?

  Audit of the statues of the device in the Device Manager.
  a. click the Start button, type devmgmt.msc and press ENTER.
  b. check for any exclaimation mark and the status of the devices.

  Follow these methods.

  I suggest you to first run the resolution of performance problems.

  Method 1: Open the resolution of Performance problems
  http://Windows.Microsoft.com/en-in/Windows7/open-the-performance-Troubleshooter

  Method 2: Disconnect non-essential external devices and try to evaluate the computer.

  Method 3:  Also, temporarily disable the antivirus and check the question.  Anti-virus programs are sometimes called causes this problem.

  Turn off the Antivirus software
  http://Windows.Microsoft.com/en-us/Windows-Vista/disable-antivirus-software
  Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

  Let us know if it helps. If the problem persists, please answer, we will be happy to help you.

• Improve the performance of processing image javaFx

  Hello

  I'm working on Image processing with javaFx. I think my code isn't effective favorite (with pictures HD, refresh is very slow). Because I am doing a 'for' on each pixel of my image every time I have to refresh it. But I don't know how else to do.

  So I need help to improve the performance of my treatment.

  This is my code:

          stage.setResizable(false);
          stage.setScene(scene);
          stage.show();
      }
  
      private void initImage(AnchorPane root) {
          src = new Image(
                  "http://mikecann.co.uk/wp-content/uploads/2009/12/ScreenHunter_02-Dec.-10-19.41-1024x484.jpg");

                  double red = (double) value * x * y / (width * height) / 255;
                  double green = color.getGreen();
                  double blue = (double) value * ((width * height) - x * y)
                          / (width * height) / 255;
                      writer.setColor(x, y, Color.color(red, green, blue));
                  }

          }
  
          public static void main(String[] args) {
              launch(args);
          }

  And that's with full HD picture:

              src = new Image(
                  "http://www.freedomwallpaper.com//nature-wallpaper-hd/hd_sunshine_hd.jpg");
  

  As you change each pixel independently, there really is no other way than to use a loop through the pixels. Working directly with the pixel data, rather than use setColor and getColor (...) (...) seems to give some performance enhancements. And there are some general performance enhancements, you can use (reorder the loops, calculate the value used repeatedly, etc.). The performance of this version seems acceptable on my system:

• How to improve the performance of the import

  I'm converting a database of its current WE8ISO88591 character set AL32UTF8
  I use NLS_LENGTH_SEMANTICS to TANK so I don't have to increase the length of the column.
  
  I followed the instructions in the Oracle:
  144808.1
  313175.1
  
  Except import that takes too long.
  
  I took a full database export WE8ISO8859p1 and now its importation in AL32UTF8.
  
  It is always difficult to prove slow source; but I think it has to do something with NLS_LENGTH_SEMANTICS. On the same
  Server; If the new database was in WE8ISO8859P1, a 5 million row table import took 2 hours; but in Al32UTF8 with NLS_LENGTH_SEMANTICS it takes 1 day!
  
  No idea how to improve the performance of the import.

  DOUBLE WIRE!
