I bought an Acer V3-771G last september and have just began to notice that my processor slows down significantly during games. I've noticed a loss of 90fps in minecraft and 20fps in borderlands 2 when this takes effect, which is after 10-15mins of ingame-time.
My specs are as follows;
Intel i7-3610QM Quad Core @ 2.3GHz, turboboost up to 3.3GHz
Nvidia Geforce GT 650M, 2GB video card
16GB DDR3 Memory
It might be an overheating issue, it might not. But for the past few days ive been running diagnostics during gaming. HWiNFO64, tells me that my intel processor decreases to just 1.2GHz during the immense fps drop i have during games. Whilst at the time of the fps drop, speccy tells me that the highest temperature my laptop reaches is 75C. Which leads me into thinking its a software problem.
Also when the laptop's under high load, when i take my charger out the processor clock speed kicks up and i get more fps for a few seconds before it eventually drops back down to normal low again
If anyone can help i'd appreciate it greatly
