1 - Can I run Blender on a Voodoo 1 or Voodoo 2 card

Contributed by anonymous.

Voodoo 1 and 2 cards don't support OpenGL, so you can't run Blender on them.

2 - Videoproblems - no card defined

Contributed by B@rt.

Problems like these are usually caused by non-OpenGL compliant videocards. Some of the more notorious ones are the 3DFX Voodoo 1 and 2 and the Matrox G400 under Windows. Please try to find out the brand and type of videocard that you have so can search here for more information.

In the mean time, the easiest trick to solve the screen problems or crashes is to disable the 3D 3hardware acceleration on your system. Blender will run a lot slower now (and will not be very well suited for full-screen gameplay), but you will be able to work with it. Here's how you do it:

Right-click on the desktop and select 'Properties'. In the Display Properties window, select the Settings tab and click on the Advanced button in the bottom right. Next select the Troubleshooting tab (Windows 2000) or the Performance tab (Windows 98) and change the 'Hardware acceleration' value. Since your mileage may vary, it is worth while to experiment with different values here. Change the value, click Apply and test Blender.

3 - What is a good OpenGL videocard?

Contributed by anonymous.

nVidia's TNT2 and GeForce 1 and 2 cards are good and affordable videocards to use with Blender.

If you already have such a card, make sure you are using the latest drivers from https://www.nvidia.com

4 - Which are known problem videocards

Contributed by anonymous.

The following videocards are known not to work with Blender:

- Matrox G400 (under Windows - under Linux it's fine)
- S3 Savage4 16mb agp
- 3DFX Banshee, Voodoo1 and Voodoo2

5 - I have the XXX Graphics Card - where can I find drivers?

Contributed by anonymous.

The 3D Chipset website has a special section devoted to drivers, where you can find both, stable and highly opimized (but maybe unstable) drivers for most 3D cards.

6 - How can I tell if blender recognizes my video card?

Contributed by Michael.

Blender doesn't look for your video card. Blender access the video through the OpenGL library's. While some video cards do not work well with OpenGL thats not directly affected by Blender. Blender works well with the Mesa library's, some of the modified library's like the one for the hardware acceleration of the Nivida TNT cards, while speeding up rendering can cause side effects in other functions.

For more information on videocards, try searching for 'videocards' (duh ;-)

7 - There seems to be a glitch in Blender performance on my win98. some images need to be scrolled over to appear. Is therenanything I can do for smoother performance?

Contributed by Andrew.

I had a problem when I found that the buttons kept moving to the left everytime my mouse moved over them. However when I increased my colour resolution to 32 bit the problem stopped.

Hope it helps
