Just finished a flight CYWG-CYYZ and 95 mins into the flight the fps suddenly dropped to mid to low teens, up until then everything was fine, and 30+ fps. Looked at my system resources, free system ram 11gb of 16gb, and 1.5gb of 4gb vram free, temps fine all around, so no issues there. Immediately (within a minute) disabled and re-enabled SMP/RWC and the issue was gone, and the remaining 20 mins of the flight were fine, back to 30+fps, same weather obviously. There's definitely a issue with SMP somewhere, something is "building up" and almost causing the system to crash. You can see it coming (within seconds), the video out of nowhere starts to stutter, everything gets jerky, and the fps plummet. The flight was fine up until that 1.5hr mark, the fps tanked, reset SMP/RWC and all is fine until the end of the flight. Most definitely not a hardware issue, for sure. If the problem was hardware, the issue would persist. As it is, the system comes back graphically just fine immediately after resetting 2 plugins. And it continues to look just the same, same amount of clouds, same demands on the system, as it did seconds before the issue started. If it were hardware this simply wouldn't be the case. There's a "bug/glitch" somewhere with software, SMP, RWC, or Xplane (beta). Also, if I do a flight with just the defaults (no SMP/RWC), where the clouds are much more demanding on my system, I don't see the issue at all. I did a CYUL to CYYZ with defaults last night and all was fine, although the fps suffered more than when using SMP/RWC. Frank, sorry I don't have more to offer. When it happened I was 100 mi out from CYYZ, just started descent, clouds were light, and that's reflected in my system/vram ram numbers above. Next flight I'll try without RWC and see what happens.

Very interesting discussion from both sides of the issue...I learned a lot! Thanks to all.
