In 107 and the previous build I've still been getting occasional graphics freezes for about 10 secs with sound still running, then the game continues with textures messed up. I think the build before that (or was it the one before that(?)) didn't have it. Turning off shadows has always stopped it when it's present. Few others seem to have this so I suppose it must be my system, but rF2 is the only game that does it.
