Hi everyone. I have an acer E5-575g laptop that has these specs:
Intel Core i5 6200u 2.4GHZ up to 2.8GHZ
4GB Ram DDR4
Nvidia 940MX GDDR5 with 2GB Vram
500GB HDD
Well i bought this laptop a few days ago and i installed games to test its performance. Actually i have a good enough system to run games like GTA V, Battlefield 4. But for example when i play gta v for about 10 minutes the game starting lag and the FPS dops from 40 to 11,10 and i can't play it normally. But in Far cry 4 with ultra settings i can play smoothly. I tested several graphics settings and even on medium i have this problem. The temperatures are fine i think. Cpu temp while im playing is about 65~70 degrees celsius and when fps drops its about 70 °C and the gpu temp while im playing is about 59~62 °C and when it starting lag its about 62~68 °C. I tested many solutions like buy a cool pad or placed a fan in front of laptop's fan or i defrag my hdd nothing helps. I hope someone can help me or tell me if anyone have this laptop too have the same problem or not
