I have trouble playing CSGO and watching stream at the same time.
When only playing CSGO i have FPS arround 240 - 340 and thats fine.
When i open stream in the background my FPS drops down to 60-80. I dont think it should drop that much. (Even my old laptop dont do the same)
I think its the graphic card, one of my friends have the same issue with same graphic card.
I know it should be possible to do both things without dropping so many FPS
Here is my Computer specs
