Recently i have been seeing my fps in Minecraft go from 400 to 60. This has actually happened in all of my games such as Garrys mod, Tribes Ascend etc. I have run a variety of Virus and Malware software to keep me safe but nothing seems to be dangerous. I do have some queries though. There is something in my task manager process list called System Idle Process which has a number 80 - 85 next to it. Which I thinks is bad but im not sure. Also When Im not doing anything my GPU usage is at 0% which i dont know if its ok or not and it gets to 30% when i play Minecraft.
I f anyone knows a fix or has a solution to my problem I would be honoured to know.
