Check for overheating: Download a temperature monitoring program like HWMonitor or MSI Afterburner to check the temperatures of your CPU and GPU while playing Diablo 4. If you notice unusually high temperatures, it could indicate an issue with cooling. Ensure that your CPU and GPU fans are running properly and that the heatsinks are not clogged with dust.
Update graphics card drivers: Even though you mentioned that you have the latest drivers installed, it's worth double-checking. Visit the official website of your graphics card manufacturer (NVIDIA in this case) and download the latest drivers specifically for your RTX 4070 TI.
