If I switch to OptiX in either c2a2cd13be2f (2.82 alpha) or 970d7ed860f1 (2.81 beta), it crashes as soon as I render image or render animation.

I cannot reproduce a crash on TOT blender-v2.81-release branch. Might have gotten fixed in the meantime. I suggest trying again once buildbot created a new v2.81 build for today.

I can reproduce.

With RTX 2080, Optix enabled Viewport Render crashes Windows 10, need to hard reset machine. Version from 2 days ago works without issues.

That's a different issue and was fixed today, see T70937. This one talks about a crash not related to viewport rendering.

I can no longer get it to crash. It's behaving weirdly in other ways I can't explain, but it does not crash so we can close this one. :)
