I think intel and AMD video card thats can use normal ram as VRAM have issues
I just noticed something on these forums. There is A LOT of people with intel and AMD video cards that use tech that allows normal RAM to be used as "Video ram" are reporting errors such as "Engine Error 0x887A0020 - DGXI ERROR DRIVER INTERNAL ERROR" Chances are how those ghx cards transfer info from VRAM, to normal RAM, it doesnt like.
Anyone with these cards can help and test?? Use the card using normal ram as VRAM, then test again disabling that feature and see if theres any improvement.
I myself ran across very similar errors in the game when I tried to overclock my video card. The moment I touched VRAM voltages I got errors jsut like "Engine Error 0x887A0020 - DGXI ERROR DRIVER INTERNAL ERROR" type errors.
So this leads me to believe that there is a problem with the game in handling video cards that can set normal ram to VRAM.
