Could not replicate in any of the RTX texture packs. Clean install the latest NVIDIA driver and reinstall your texture packs in the marketplace.
This is a duplicate of 5 other posts. 1.14.60 is not the RTX version of the software. Clean install your graphics driver. reload the asset packs in the marketplace. Turn off all overlays and fps counters. play in fullscreen with DLSS and RTX ON. if the issue persists let me know
Rollback your driver to the previous version. If the problem persists it's not the driver. If it goes away try a clean install of 445.87. If the issue is with the driver after update just dont use the driver
Do you happen to have ultra low latency enabled in NVIDIA control panel?
Edit 1: make sure your monitor isnt running at a low refresh rate which would, regardless of your fps, cause significant lag
Assuming this is an RTX map redownload the assets. Ensure that you have the latest video driver that NVIDIA released for RTX beta.
Which RTX map is this?
I know D3DDRED2 is NVIDIA based driver issue. are you overclocked at all? try a clean install of drivers. Maybe even DDU I would recommend downloading DX runtime again from Microsoft as well as Visual C++ which is ucrtbase.dll. Other than that you said the game ran fine before RTX so other than a driver clean reinstall that's what I've got. Disregard if you've already done so.
EDIT 1: Also it is shown in other non-RTX games that overlays (Steam, Discord, Windows Games, MSI Afterburner) can help cause this type of crash
Checking the forums for you but this is definitely an NVIDIA error
