After getting my 6670 DDR3 to pair up with my 965 BE, I decided to look into a bunch of my old games; found the amazing Neverwinter Nights game. Considering how I upgraded from an x300 SE, I thought I'd be able to run this game without a hitch.
It turns out that AMD has utterly crippled the OpenGL performance in their newer drivers. The driver package 9.10 is the last one to not cripple OpenGL performance. From that to 12.1, the framerate plummets from the hundreds to around thirty maximum. Using any new package results in the sub-30 region, making the game completely unplayable.
Using an OpenGL-DirectX wrapper allows you to get up to around 35 fps when staring at the ground (I.E, only rendering a single flat plane and a low-poly character).
Many people experience this problem, and it's been discovered that it's all on AMD's end with the drivers. People who have, say, a 7850 but are using the latest drivers when playing this game, will maybe get 40 fps when using the wrapper. Same goes for the 470 (por ejemplo).
So, AMD. Why did you decide to cripple a supreme game? Neverwinter Nights is the best RPG out there. Even though it's more than a decade old and was designed around the Ati Radeon 7000, today's AMD GPUs cannot run it satisfactorily due to bastardization of the drivers.
