There has been a lot of negativity surrounding the PC version of Grand Theft Auto IV. Most notable is the incredibly poor performance on many PCs as Tom’s Hardware reported on earlier this week. NVIDIA this week quietly released ForceWare 180. 84 beta which
The 180. 84 beta drivers are having a mixed reception. Some users are reporting a mere 10 FPS increase in performance using the game’s built-in benchmark while a large number of others experienced no change beyond margin of variation between benchmark runs. Several users noted that while their framerate did not increase significantly, it was more consistent during play.
On the other side of the playing field, some users had drops in performance and others had problems to even run the game; receiving the infamous "RESC10 - Out of video memory" error which didn’t occur for them using older drivers.
The ForeceWare 180. 84 drivers unfortunately did not help in fixing texture and shadow problems that have also plagued the game, and do not allow anti-aliasing to be forced on through the driver control panel.
It appears that the driver should be avoided for now, as it's still in beta.
