You can't (certainly not manually anyway), and if you could, you wouldn't want to (system memory is much slower).

you can't share system ram with the graphics card. Anyway why would you want to it would slow things down. Your card should be fine

It'll already share system ram automatically if it needs to ... unfortunately, as other have said, that can slow you down substantially.

Here's some hints on getting good performance despite low VRAM amounts: use lower texture size (aka quality) settings, don't use AA, and don't use VSync.

Also, the rivatuner graphing tool can be real handy. You can put your vram usage up on screen while you're gaming, and by this means see the effect of settings adjustments on memory usage.

BTW, usually you won't start really taking an fps hit until you use up over 300MB of local vram with a 256mb card. Most games out there, this just means using a texture size one or two notches down from the max, and not using AA or vsync, to keep under your vram limit.

Not very well, if you could get it to imo

Even the fastest rigs today can only get about an average of 50 fps

>$3000 can get you about 30fps

If your lucky you could get around 20-30fps
