I have an ELSA GLADIAC 511 64MB GEFORCE 2 MX 400 and I'm running the latest drivers from ELSA that were made for this card. Perhaps Nvidia drivers do a better job of this? Then again the drivers may be the same just with the ELSA logo instead.
I'll wait for the full game tomorrow

and then if I have problems I'll try some of the programs you guys have kindly listed, thx.
