While there is an apparent wide-spread issue as mentioned above, it’s not effecting everyone equally and only applies to people who have updated their GPU drivers. I’ve done some quick looking into these issues on the back ends based on your forum usernames, and have noticed the following about a few recent comments.
@alt_g You seem to be running the Nvidia 451.67 driver from June, please update your drivers and see if that resolves the issue. The most recent is 461.40 from Tue Jan 26, 2021.
@Rats_Beyfus You seem to be running Intel Build 220.127.116.1129 from September. The most recent intel driver is 18.104.22.16868 from 1/20/2021
@Bart_Simpson2 You seem to be running Intel Build 22.214.171.12481, also from September. The most recent intel driver is 126.96.36.19968 from 1/20/2021
Zwift runs best on updated drivers and old drivers can cause instabilities in your systems, so please make sure to update your GPU drivers if things aren’t working properly. If you update the drivers and the game is still crashing, we would love crash logs and game logs from anyone who hasn’t already sent them into us. The more data points we have, the quicker we can pin down specific issues.
As an additional note, we are unbelievably busy on the support team at the moment, so it may take us a while to respond to emails, but we are working through all messages in the order received as quickly as we can!
Thank you for your patience!
