  • CS2 Performance - Intel 12/13/14gen users should DISABLE E-Cores!
    CoreDirector is pretty straight forward and easy to use, but on my machine it caused micro-stutters even if I had higher frames. I used Process Lasso to do this, which should be the same thing CoreDirector does, but it worked better for me. Source: 7 months ago
  • Another (possible) Fix for the 5 seconds stuttering (Even on SSD)
    If BES doesn't work for you, you can try Project Lasso for free: https://bitsum.com/.

    I use process lasso to assign priority, cores, powerplans and 0.5ms timer resolution to processes to improve performance. (something to manage a process once run like powerplans). Source: 8 months ago
  • Far Cry 4 stutters killed me
    All right, here are two possible solutions I know of: Firstly you can limit the number of cores the game is using, which can increase your FPS significantly (and potentially fix the stutter as well). Why? Because Far Cry 3 and 4's optimalization on PC sucks ass, and the newer the PC setup, the more likely it will have problems with both games. How to set CPU affinity: 1. Open the game. 2. Once in-game, press... Source: 12 months ago
