I have a 6-year-old laptop 3rd gen Intel i5 with Nvidia 640m. Comparing its performance while playing dota2 3 years back to its current performance --> from 60fps medium settings(70% texture) to 30fps(40% texture) low settings I understand that the game engine has changed, it used to put out 60fps(maybe bit lower settings) in the new engine as aswell . I think the main reason is that CPU and GPU are not being efficiently cooled because when i check temperatures its arround 80c although i am not sure if the performance of electronic components degrade overtime. can someone tell me what might be wrong? I am considering changing thermal paste for now.
