I've never had an issue with rendering before, even when all my graphics settings are on high, but for some reason for the past few days my horses aren't rendering at all & look blotchy, even in CAS.
Does anyone have any ideas?
Mine started to do it when my disk was running a little high. I transferred my 40GB+ video folder onto my harddrive and my game improved.
Is it possible you're running low on disk space?
It's also worth noting that when this happened to me last time, it was also because I had a lot running on my laptop at the time.
