“Rendering Device Lost!” with RTX Graphics Cards
There was previously a semi-common problem with RTX graphics cards receiving this error message, however the issue has since been resolved with the latest Nvidia Geforce drivers . Before troubleshooting your individual Rendering Device Lost error, try updating your drivers as mentioned in this post .
If updating the drivers does not fix your issue, then the problem is unrelated to the previous bug between RTX cards and Overwatch. Please feel free …
I know the “render device lost” bug has been making a comeback with the new nvidia RTX series graphics cards. I recently upgraded to an RTX 2070 and started to experience the the issue as well. Many threads say that overclocked cards is the cause as Overwatch is very sensitive to instability. I have attempted to underclock my MSI RTX 2070 Duke 8G OC back to stock values with no avail.
However, I then tried underclocking the memory instead of the core clock and it seems to have fixed the problem…
Personally, I get the same errors depending on the patch on a non-Nvidia card if I run much of anything else at the same time. It’s just life with Blizzard games.
