However, I was still experiencing extremely low frame rates benchmarked at about only 7. In GPU-Z I noticed that my GT 650m GPU was grossly underclocked at only 135mhz while the game was running when the default frequency is 745mhz, and the Intel GPU was overheating. After some digging, I disabled Intel StepSpeed, which dynamically manages frequencies of various processors, in the system BIOS and now the GeForce GPU runs at the correct clock speed and Intel GPU no longer overheats. The game now benchmarks at 32 fps at medium setting, which is acceptable for GT 650m. This fix should work until the next driver or patch update (I hope), since it shouldn't be a permanent solution when overheating, battery life, and chip life are concerned.
Wow! That worked, mostly. Now getting 30FPS in most areas and 18 at the Crossroads (up from about 15 at best and 5-6 at crossroads). Occaisonally will get a weird hitch that lasts for under a second.
