Moin, I've been playing on my gaming laptop for almost 2 years. The problem is that for the last 3 days I no longer have 160-200 fps everywhere as before, but suddenly only 25-35. What can be the reason? The games are GTA V, battlefront II, and Minecraft. The fans turn just as loud as before.
It could be that you have downloaded some unnecessary programs. Delete them out. And press the Windows key -% temp% - enter. Delete the files there. They were all temporary files and are now completely useless
I can do it, but haven't downloaded anything lately
