audio bug and graphics glitch

[tomoose]

G'day,
I'm using latest TM, RSRD. A couple of things I've noticed perhaps someone can indicate whether they are 'fixable' or not.

Graphics glitch;
the sea motion seems to "reset" it's overall motion every 8-15 seconds. Kinda hard to explain without video but the sea motion is doing it's thing then every so often it seems to "shift" or 'reset' and carries on as per normal. Visually it's slightly annoying but doesn't seem to affect game play. This is not the shuddering after dropping out of TC, I don't have that problem.

Audio 'glitch'?
Once in a while (i.e. rarely but...), haven't been able to figure out why but there is a goddamn awfully loud sound like blowing ballast/air. Loud enough that I have to remove my headset. It last a few seconds then back to normal.

Has anyone experienced either anomaly?
thanks,
Tomoose
