Hello. I've been getting this happening for quite a while now... I've tried to explain in words what is happening but people don't seem to understand what "tile textures skipping either half or full tiles when moving" means... can someone PLEASE tell me what is causing this? I show you my settings (after re-downloading it) so people can see what is wrong. I'm on a late 2011 iMac with Lion 10.7.4 installed. All software up to date. [media=]http://youtu.be/wDY7U2suZKQ
