Pink soup after 200 hours

I have legacy edition on steam. About 15gb content, 16gb ram, GeForce GTX 1050 Ti, backdated my drivers as it seemed to have got worse after the recent March updates, however now I think it was just coincidence.

I've had pink soup, red soup, grey soup (?) - I've had the lot. 

Can't figure out a fix. EA, you really need to get onto patching this issue. 

I also get this error code in my cheatbox (with the latest nvidia update anyway, haven't checked since backdating)
