i have this problem on rainbow 6 and overwatch at the moment. i also play heroes of the storm, europa universalis4 and many other games. but they are pretty smooth 60 fps. when i launch overwatch or r6 fps suddenly drops to 15-20 after 3-4 mins. even sounds are freezing/lagging. whenever i go alttab and go back it becomes 60 fps again for like 5-10 seconds. the tempeture about 80-85 celcius when fps drops. my specs are;
