I've reported Global Illumination change from high>med - crashing to Epic Games. I will see what will happen. Crash happens also if AA=TSR & upscaling=built in or upscaling is FSR. Are you sure error isn't on your side?
GI=disabled - OK // GI=LUMEN & reflection=LUMEN, (everything low), GI med>high OK BUT THEN crash when OVERALLQuality custom>right = CRASH // condition TSR FSR Quality or TSR built-in.
That error is strange - Sometimes doesnt happen, until I change condition: TSR built-in 100 to TSR FSR Quality then TRIGGER is (everything low) THEN crash when OVERALLQuality custom>right = CRASH // condition GI=LUMEN & reflection=LUMEN
Once I reported 1 Nvidia error (send apps log files) and they reported back that they solved the error and will be repaired in their next app update and this error is fixed =)
