DC "fix": "Better" watchdogThread. Need to be tested on others PC specs. Everything works with for me (nice Q6600 + 8800GT owners :p ). We may have to put some hardcoded value in GUI for helping debug on other PCs. If it doesn't work and if someone have time, tweak a bit the threshold "FourMsCount" in "GPWatchdogThread" and let me know.
