On Thursday of last week (4/5/18) I was running 100 frames on all low settings, but since then, I have been running 40 frames. This usually happens after I get into a game. I will be at 60 fps in menu, 100 when picking a hero, then once I get in game I run 30-40 frames. This continues until I restart the game. I have done everything I can think of to fix this.
In task manager, while in game my CPU is at 20-30%, my RAM is at 60-75%, and my GPU is at 100%.
Another help that could be given would be greatly appreciated, as it effects my performance in game and is making it hard to play overall.
