Need For Speed :: San Andreas

Hello everyone,

So my PC 4GB RAM, CPU Intel pentium b970 2,3Ghz (2 cores)  , and GPU nvidia geforce 610M + integrated GPU, and it should work on stable 61FPS but i have huge fps drops.  If I want to play MTA or GTASA I cant choose (High perfomance NVIDIA processor) it automatically starts working on intagrated GPU. So what I should do? On other games works everything. So what I should do?

I think you should rather post this on MTA forums, though.

I think it has something to do with the current power plan your laptop is on.
