witcher 2 - on new drivers?
I thought I'd give Witcher 2 a try (before getting into 3) on the 350.12 driver and although it looks great, really great, the performance is lacking. I was planning to upgrade my system but wanted to explore the performance issues first. I have an i5 2500 at 4.5ghz running a GTX780, although an older card the 780 is barely being used, with usage of 30 to 40% whilst the CPU is being pushed from 70 to 90%. It seems the game is not very well optimised on this driver and probably other newer ones? I was wondering if it was this CPU heavy before on older drivers as appears to be a bottleneck? I have done a bit of research and lowered all settings to the minimal possible and the frame rates still dip to 30s 40s with GPU only being utilised and 40% at the most. Its very annoying because the game looks incredible in 3D, this effect sometimes feels like a curse as I will do nearly anything to get it working in some games lol, even looking at some of those tutorials! its amazing to me that a larger audience don't appreciate this effect, it makes Witcher 2 a different game.

The performance in Witcher 2 on the latest drivers is great (Windows 7/10) I finished the game again last month in 3D Surround using 2x780Ti GPUS : 60 FPS in 3D Surround both GPUS are used 99%. The fact that you CPU is used 70-90% and your GPU only 40% suggest a CPU bottleneck. Simply put your CPU is not fast enough to satisfy the demands of the game and is slow in "pushing" data to the GPU. If you are on windows 7 you can DDU and remove your current drivers and install the latest ones 355.60. Try the game again and if the same issue it definitely looks like the CPU is at fault.

thanks helifax appreciate the tip. I will give that a try before I give up on the cpu, I have a feeling there could be a problem with it. Many thanks

I just finished a play through using 350.12 in 3d Surround for a save for the third game. and I also just upgraded from a 780 SLI setup to a titan X. Performance in surround was actually comparable.

i had actually purchased witcher 3 with the intention of playing after 2 so did a test run on the first few areas, the bizarre things is TW3 performs great, barely any slowdown! much better performance that TW2 in 3D, and the GPU is in the 80% area. so for some strange reason witcher 2 (with minimal settings) on my system destroys my processor and barely uses the gpu...
