Overwatch ran below 100 FPS with GTX 1070 at Epic settings, while the RTX 3080 improves it to the monitor’s refresh rate even at Epic settings, though it can go further than that but I have limited the frame rate below monitor’s refresh rate to avoid screen tearing. Temperature is something that I am pleased with Asus TUF RTX 3080.
