hello everyone. I hope all is well.
I'm telling you that I have a problem with the darkshader distort.fx call effect. When playing for several hours, the effect drops its framerate drastically to approximately 15fps and the game continues to be at a stable 60fps. The funniest thing is that if I restart the PC, it resolves itself, but after hours go back to the same thing. It is as if a memory cache was put together. thanks for your help. Greetings.
