I just played game of Fortnite on these settings just turned down view distance to low and lock at 60FPS. I don't know if the problem is cause I run 2 monitors ? I lock my fps to 60 cause of CPU usage, but even then I get drops to 20-30 FPS in closeup fights. Here’s how to force an app to use the NVIDIA GPU on Windows: Right-click on your desktop and click on NVIDIA Control Panel.
They'll be found for global settings in nvidia control panel, or per game in GeForce Experience or game graphics settings. There are some, like physX, grass details, viewing distance that have bearing on the cpu. On most platforms, you simply reboot the system and click delete or F2 repeatedly as it restarts. Resolution and most game details are the gpu issue, got almost nothing to do with the cpu at all. Its pretty simple to enter the BIOS to check your CPU temperature. If you want to use the integrated graphics card, select Integrated Graphics. Select the preferred graphics processor in the drop-down list. Select the program you want to choose a graphics card for from the drop-down list. Many games are making the move to optimization for 8 threads or more, they'll work on a 4c/4t, but the cpus are so packed that it's not uncommon to see upto 100% usage. Under 3D Settings select Manage 3D Settings.
