Have you tried the following?
Open up "NVIDIA Control Panel" -> from the NVIDIA Control Panel, select the "Manage3D settings" from the left column -> click on the Power management mode drop down box and select "Prefer Maximum Performance".
Seen this on GTX 1080s, another option is to disable DX12 from ingame
You can also see if disabling or reducing any overclocks are causing issues. My friend had an issue with a RTX 2070 that was crashing until he removed all the overclocks from his GPU, CPU and Memory.
