Can someone explain this problem?

This would be the second time this has happened while running fsx. I will post a screenshot. It appears to be a memory issue or graphic issue. The first time this happened I switched out video cards. Now its happening again. Overheating? I dont think so, the video card doesnt exceed 55C underload in fsx according to Hardware Monitor. Ram? the game runs capped at 3.8GB hasnt crossed the 4.0GB limit. Once this happened I went in to reduce settings, this did not fix the issue, it made it worse. The simulator turned black, but it was still running. Before that the water was gray and the terrain was very low detail. This picture below shows where the problems started. Notice all the switches are blacked out. and the gear arm has vanished.

no one? I know this question is quite complicated? but if anyone can help. I appreciate it! Perhaps a graphic card driver update will help? Mine is about one update behind the latest one.

No ideas. I have never had such a problem with my GTX 570, or are you currently using the 5770.

Double-check you are using HIGHMEMFIX with the correct spelling. Tim

you know what? that was never in my cfg. and Now I believe my gtx 570 was fine. I bet the mem fix was the issue all the way, not the card. because I can run any other game just fine.I also just installed the shader 3 mod as well. Hopefully that wont interfere with REX 2.0

[sho69607 27]

yep the memfix fixed the issue. I cant believe I overlooked that. Im back to using the gtx 570 now, and its working fine. Temps are a bit higher under load but not much only about 65Cand the shader mod screwed things up at first so I removed it.
