Far Cry 2

The improvement is obvious compared with GeForce 182.08. However, if you install GeForce 186.18, you may experience small performance drop that is why GeForce 185.85 version is currently the most optimal choice for Far Cry 2 game. The only case when you should upgrade to version 186.18, is if you experience any issues with version 185.85 functioning; however, we haven’t had any problems so far.

The developers claimed that in games based on Source engine the performance would improve only in 3-way or 4-way multi-GPU configurations. However, things turned out a little more complicated than that. When we upgraded from GeForce 182.08 to GeForce 185.85 the gaming performance dropped! It was not dramatic or even serious, but the fact was undeniable: the new driver proved less efficient than the old one for G20 based graphics accelerators. Installation of GeForce 186.18 resolved the issue: performance went back up and even improved compared with what we got with version 182.08.

The situation is different with G92 based graphics cards. Versions 182.08 and 185.85 performed equally, while with GeForce 186.08 driver the gaming performance dropped by 9-14% depending on the resolution. So, the owners of GeForce GTS 250, 9800 GT/GTX/GTX+ graphics cards and maybe also solutions on more powerful Nvidia chips, like G94< should better stick with version 185.85.
