The 256MB is just the aperture size. Steam's VRAM detection is completely broken, so it reporting 268.12MB or whatever is bogus and has no effect on performance. I don't think upping the aperture to 512MB would make any real difference in performance.
OK, thanks for looking into it.
I had an issue with video tearing on Ubuntu with mythtv frontend and tried the TearFree option in xorg, which fixed the tearing but made the video stutter occasionally (only in myth, not in kodi). I have now removed the TearFree option and installed the compton composite manager, which so far looks like it's fixed the tearing without stuttering.
From memory, someone mentioned dual channel ram might also increase performance, so that might be another option if I find some cheap enough.
Sorry to get off topic.
