February 20Feb 20 Short message: MSFS SU5 beta crashes for me with dev mode on and FG on at the same time. ------ In the latest SU5 beta, I could not figure out why turning on FG was suddenly crashing msfs24. I had been using the beta in VR without issues (because FG isn't used in VR). So when I tried 2D mode today the sim instantly crashed when I turned on FG. And then msfs24 would no longer load up, it would hang at about 54% loading. A google search finally showed me that Dev Mode was the issue. Reference: "After an hour trouble shooting thinking it was a driver issue, I think the issue might be with developer mode. If dev mode overlay is enabled, frame gen doesn’t seem to work properly." https://forums.flightsimulator.com/t/frame-generation-working-at-all-in-2024-4080/670045 By the way when you turn on FG with Dev Mode on and msfs crashes, then it will still overwrite UserCtl.Opt and put FG and Derv Mode both on in UserCfg.Opt file text. And then the sim will not even boot up!! hangs at 54%. So I had to first rename UserCfg.Opt. And then msfs loaded fine. And then turn Dev Mode Off. At that point I can turn FG on or off and it msfs work and not crash (as long as Dev Mode is off). 5800X3D, RTX4070, 600 Watt, one or two 1440p 32" screens, 64 GB RAM, 4 TB PCle 3 NVMe, Warthog throttle, VKB NXT EVO stick, Honeycomb Alpha yoke, CH quad, 3 Logitech panels, 2 StreamDecks, Desktop Aviator Trim Panel.
