An update re my last reported downgrade to 126.96.36.19985 - 5 days of riding, 300kms without a crash. Not getting my hopes up too much just yet - did have similar crash free periods with more recent drivers. And as Dave said and as per advice from Zwift, you may need to try using other non PC devices to reduce crashes.
I bought a new, faster Dell laptop in December following the specifications guidance provided on Zwift’s setup webpage. I continue to have crashes during rides 30 to 45 minutes into the ride. I haven’t tried to downgrade the graphics driver yet. However, I have pulled out the old laptop and had no issues in my last 4 rides.
Still crash free 10 days/many k’s down the road
I’ve switched to using my older laptop (4th generation processor) and haven’t had a crash either.
