Hmm, it does sound like a heating issues that is causing these anomalies/artifacts.. Do you guys keep an eye on the temperature in game..? It shouldnt be going over like 77max or 80MAXX.. Mine is usually around 75 fully overclocked..
Also does it occur in other games or just ps2 ??
It could also not be related to heat but instead be a in-game glitch.. Because even i have had some weird things happen to me once in a while in ps2, like all the buildings and stuff start dissapearing and flashing greyish and also i lose alot of fps.. But then i go into the warpgate and chill for a few mins n it goes away.. So if it is not a heat issue and there is no similar problems in other games, then there shouldnt be anything to worry about, just complain on the ps2 forums for the devs to fix it
