My graphics driver was recently updated. I have cleaned/repaired dcs and reinstalled. Neither resolved the issue. My install is pretty fresh so do you still recommend clearing the shaders folder?
I did find something that does seem to help. Downclocking my vram down 200mhz using MSI After Burner seems to stop the flickering and stops most of the crashes. I do not experience crashes in any other games using stock VRAM speed so this seems like this is something specific to how DCS deals with VRAM.
