While playing bf4, my GPU clock speed starts out fast and very good fps (40) is reached. However after a while and the temps have increased from 76 celsius to 93 celcius, the core clock goes from 797 mhz to 668 mhz and the fps cant get above 15 and so much stutter renders the game unplayable. I noticed at 90 celcius and 99 percent load, the clock speed goes from 797 mhz to 720 mhz and then as temperature comes closer to 93 celsius it decreases even more. I've never seen my gpu go above 93 celcius so I suspect that my card reduces its clock to save it from high temperatures.
I want to disable this completely, but don't know how. GPU is geforce gt 630m and cpu is i3-2350m cpu clocked at 2300mhz. Trying to OC both gpu and cpu atm, will update thread.
