I see the problem.

You were on zwift too early. Computer wanted a sleep in.

I guess your computer needed a day off.

That DLL file suggests your GPU in some way. Are you running multiple monitors? Is threaded optimization turned off? Recently changed your driver or applied an overclock? Just a few questions I’ve seen dotted about in relation to that DLL and games crashing.

Wait look at that exception data. That’s a bond issue…James Bond.

(Sorry, can’t help myself)

Thanks @DaveH for looking at this.

On thing I changed recently is I changed Vertical sync to ‘Adaptive’. But I have ridden a few times after that change with no issue.

LOL that was after a 30min warm-up :rofl:

Looking at your recent post on ZPCMR, you’re actually running a quite recent driver. If you updated that from a very old one, perhaps it could do with a clean install. Have a Google for DDU.

PC was rebuild recently March time frame. I keep my drivers updated I check for updates weekly. I updated the GPU drivers today (after riding today).

But a clean install of the GPU drivers can’t hurt.

Looking at the release notes for the Latest Nvidia driver.

If it can impact F1 2019 it could probably impact Zwift.

@DaveH I just did another ride and all was well and good. Lets hope this was just a gap in the matrix.
