Thanks for your comment! Please excuse if I got the nomenclature wrong, what I meant is simply video memory in general. In the case of the FX 5000 Series, it is DDR video memory with a 256 bit bus width.
Sure, Voodoos or a Riva TNT2 "only" have 16-32 megs, which is certainly sufficient for Unreal or Duke 3D, but I really would like to run more recent things like Wolfenstein 2 etc. with brute force 8x AA and AF at 1600 x 1200 (which is possible on the FX series).
Do AA and AF increase video memory usage? Texture size is the most important factor and should remain the same, right?
My understanding is that Textures, Zbuffer, and Alpha Blending chew up the MBytes while AA & AF chew up the MBytes/Sec (memory bandwidth) which would be memory bus x memory speed.
Generally, you can compensate for lack of MB by having a faster bus, CPU, or GPU. You can't do too much about lack of MBytes/Sec other than turn down the settings.
Best look up the requirements of the game you want to play.
Wolfenstein 2: https://www.pcgamesn.com/wolfenstein-2-the-ne … em-requirements
Minimum specs (720p 60fps at low):
- CPU: Intel Core i7-3770/AMD FX-8350 or better
- GPU: Nvidia GTX 770 4GB/AMD Radeon R9 290 4GB or better
- RAM: 8GB
- OS: Win7, 8.1, or 10 (64-Bit versions)
