@Ludicrousfox there is a bug thread for this, and it's answered there.

Cattle And Crops Tech Demo Bug Thread

But the answer is either update your graphics card drivers or change your resolution. Dropping resolution seemed to fix a lot of these issues.

Changing res doesn't work for me. I'm running the latest nvidia drivers too. Do you know if it supports SLI natively? Or are there working bits to improve performance as I'm using a pair of GTX 670's so really need SLI to work to get acceptable framerates?

That aside, I can't get rid of the big grey blotch across my screen, which just renders it unplayable for me at the moment.

Cheers,

Mark.

Interesting hopefully someone has a fix for this. I'll post our info in the bug thread

Ok, I didn't realise that there were drivers released today. I updated and the grey artifacts went away. Performance is absolutely terrible for me though. Can't hold a decent framerate. Hopefully this can be improved on.

Yep hopefully, to be fair it is an early demo build so I guess it's ok.

Had the same issue with 1 month old NVidia drivers. Updated to current version and problem is solved.
