Video Card and General Troubleshooting for PC Video Games
This trouble shooting guide is created for AMD and Intel PC's running Microsoft Windows XP, Windows Vista or Windows 7 and using an nVidia, ATI Radeon or Intel Video Card or on-board Video Graphics with shared memory.

Display and Graphic Issues
Common examples of these issues include missing textures, scrambled video, flashing areas, or a solid colored screen. Graphic corruptions usually occur when a game is using a graphics feature not supported by the graphics controller, the graphics driver has an issue, or there is an issue with the game
  • Update the graphics drivers to the latest version. If drivers are not available from the system or motherboard manufacturer.
  • Check the web site of the Video Game manufacturer for any Video Game updates, patches, or known issues with the graphics adapter. We also have Intel Video compatibility lists in the N00Pwners PC forum.
  • Make sure you have the latest version of DirectX* installed on your system. The most Video Games include the version of DirectX required on the Video Game CD/DVD, but an updated version can sometimes help to resolve an issue
  • Use the in-Video Game Options Screen to turn off any features not supported by the graphics controller.
Settings in the OS and System Hardware
Many overall system features can affect Video Gaming performance.
  • Check the memory bandwidth settings DVMT
    PC100 = single data rate memory at 100 MHz
    Bandwidth = 64bit x 100 MHz / (8bits/byte) = 800 MB/sec
    PC133 = single data rate memory at 133 MHz
    Bandwidth = 64bit x 133MHz / (8bits/byte) = 1064 MB/sec
    DDR200 = double data rate memory at 200 MHz (100 MHz x 2)
    Bandwidth = 64bit x 200 MHz / (8bits/byte) / (1024 MB/GB) = 1.6 GB/sec
    DDR266 = double data rate memory at 266 MHz (133 MHz x 2)
    Bandwidth = 64bit x 233 MHz / (8bits/byte) / (1024 MB/GB) = 2.01 GB/sec
    DDR333 = double data rate memory at 333MHz (166 MHz x 2)
    Bandwidth = 64bit x 333 MHz / (8bits/byte) / (1024 MB/GB) = 2.60 GB/sec
    Dual Channel DDR400= double data rate memory at 400 MHz (200 MHz x 2)
    Bandwidth = 64bit x 400 MHz x 2 channels / (8bits/byte) / (1024 MB/GB) = 6.25 GB/sec
  • Page File Size
    Page file size should be set to a minimum of 1.5x and a maximum of 3x the amount of system memory, as recommended by Microsoft
  • Page File Location
    For maximum performance, set the page file on a separate physical hard drive this also gives you less fragmentation.
  • Disk Space
    Many Video Games have their own temporary files and therefore require available hard disk space to run properly. Check the Video Game documentation for any free disk space requirements.
  • Hardrives
    Faster RPM is equal to faster read/write performance.
    Disc Cache should be at least 2 MB recommended for Video Gaming is 8 MB
    Bus, serial ATA is the latest desktop hard drive technology.
    Serial ATA initially launched at 150 MB/sec transfer rates, Generation 2 drives launched at 300 MB/sec transfer rates while SATA III is expected to increase to 600 MB/sec
  • File System
    Perform basic file system testing, Scandisk*, CHKDSK to find a fix errors.
System Settings.
This are some system settings and hints, they can help you to locate a problem
  • Check the CPU Usage using Windows* Task Manager (Ctrl+Shift+Esc). Watch the CPU Usage in the status bar of this window for several seconds. If usage remains higher than about 15 percent, check the processes tab to see which programs are using excessive system resources. (Facebook, Windows Messenger etc.)
  • Check that background tasks are not running, like virus scanners, task schedulers, remote system control programs, or any other programs that run in the Windows* task bar.
  • Many Video Games try to switch to this particular screen resolution and color depth when loading the Video Game. Switching to this mode manually helps you decided if the issue is with switching video modes or with loading the Video Game.
  • Reduce the desktop screen resolution and color depth to 1024 x 768 and High Color (16-bit) color depth in Display Properties.
  • Some OpenGL Video Games try to run at the current desktop color depth.Sometimes graphics adapters do not support 3D acceleration at higher than 16-bit color depth, so they can not use OpenGL 3D acceleration at true color (24-bit or 32-bit color depth).
Online Video Game Trouble Shooting

Can't access the Video Game server
  • First, make sure your computer is connected to the internet and that your firewall not blocking the game.
Cannot connect to other players locally
  • PC Video Games utilize a variety of port numbers to establish LAN connections.
  • You may need to modify or temporarily disable network firewalls running on the PCs to unblock these ports.
Lag while playing
When lagging, your view of the Video Game action falls behind that of other players, and the Video Game may also occasionally freeze for short periods.
  • Cause of lagging
  • Dial-up and satellite connections result in very high latency/ping to MMORPG's and online games in general. The bandwidth is typically not the problem but the high latency (Ping) needs to be avoided.
  • High latency of your Internet connection - consider changing service providers
  • Excessive network traffic being generated on the home network and or the Internet.
  • Stop any file sharing programs running on your PC and on any other family PC on the same Network.
Diagnostics
  • Use a Ping Tool and ping the IP Address or Host-name of your online Video Game server.
    Several free ping tools are available on the Internet for download.
    With Pingtest.net you get the ping and Jitter results over a measured time period
    With Speedtest.net you can easily check your PING and the download/upload Bandwidth (speed)
  • Bandwidth
    If you have more than 10 kb/s you are fine for most MMORPG's.
    With an internet speed of 0.256 Mbps or more, you're fine and the email program can still run in the background.
  • Packet Loss
    Much as it sounds, if you have anything less than complete success in transmitting and receiving "packets" of data then you are experiencing this problem with your Internet connection.
    Anything greater than 0% should cause concern.
  • Ping
    This measurement tells how long it takes a "packet" of data to travel from your computer to a server on the Internet and back.
    A result below 50 ms should be expected for Online Video Gaming
  • Jitter
    Zero jitter means the results were exactly the same every time, and anything above zero is the amount by which they varied.
    Like the other quality measurements, a lower jitter value is better.
Slow Video Game Servers
If the Video Game Server is on its limit and suffering from performance problems, there's generally nothing you can do.
  • If possible try, another Video Game Server.
