Would you mind if we try to really find the cause of the problem instead of just fixing it for your setup? It'd greatly assist me in fixing the problem for other users too.
I'm very sure that disabling ground decoration and reducing RD will definitely fix the problem. Now, I'd like to experiment a little and see if I can fix the actual issue, because the graphics card should never report out of memory, it's supposed to deal with its memory management on its own.
Anyway, can you restart your game and use the old settings and see, if the client still crashes? If so, please upload the new crash log file.
Thank you.
