I've been trying to get into the Witcher again, but I have encountered an unusual problem. After a while, my computer starts to overheat and the game slows down. The weird things is that I did not previously have this problem on my computer. I suspect that in between then and replacing my HDD, some setting or another got reset that is causing this; this seems to be confirmed by other non-CPU intensive games (ex: FTL) having this problem where previously it did not exist. Can anyone provide me with data to help remedy this situation?

It could be the GPU that is getting too hot. Try forcing V-Sync in the graphic card's control panel.

I was about to say I'd tried that, but just remembered that I had recently set the affinity to use only one core (I use a multi-core T520) with VSync disabled. Maybe the combination of the two will do it.

EDIT: Nope, that didn't do it. I got about a half hour in before the FPS dropped through the floor.

So it's a Lenovo T520 and you set affinity to the dedicated Nvidia GPU thus the integrated Intel HD chip isn't used, right?
The bad news, a closer look at the T520 revealed that it's rather built for business environments and prone to overheating in gaming situations. The model with two GPUs (Nvidia and Intel) might fulfill the specs for gaming, but the Nvidia produces extra heat, that the cooling system isn't able to cope with. You'll need to reduce workload from both CPU and GPU and ensure optimal cooling. Don't put the laptop on soft surfaces, clean the cooling system (see manual p.89) and if you're techy apply new good quality thermal paste.

Shut down all other running programs, especially anti-virus and reduce in-game graphics quality. Stay with your current resolution and try lowering anti-aliasing and shadow quality as they have the biggest effect on framerate (and lowering them doesn't hurt the visuals much).

I had already set the graphics to the minimum, but I'll definitely look into the rest of this. Thanks for your help.
