Crashing at hero switch

I have been crashing when switching heros multiple times. it has been happening for a while and i thought it was my GPU, Bought a new GPU and am still getting this error. reinstalled overwatch, game client and all the files without any luck. last 6 months+ of patches and it has been the same. it isnt very frequent but it still happens at the worst possible times.

RTX 2070, nvidia patch 419.35. when i googled the error it refers to the graphics card and what patch its using (might be a computer error, but it only happens in OW for me)

Edit: error is “your rendering device has been lost”

The error message occurs for Overwatch whenever your graphic card ceases to work. Since you have a RTX graphics card please refer to this thread in the technical support forum for advanced tips to resolving this error:

I also have this problem! After the update to 419.35 i get “your rendering device is lost” Its very frustrating!!

Is there any fix for this? I cant llay anymore because of this. My computer is 1 month old with a RTX 2070!

Help!
