the current Test Version 4.4.8-test18 (older ones too I guess) doesn't recognize the usage of FrameGeneration in the new MSFS 2024 SU2 beta 1.4.7 any more. Neither using the current Nvidia 310.1.0.0 DLSS 4 version nor the AMD FSR3 version which came with the new beta. Always detects that the sim is running without FG. Scannnig the FPS without using FG works fine.
Using the newest Nvidia FG Version 310.2.x per Nvidia Profile Inspector works in the sim, but AutoFPS doesn't detect the FG Mode neither.
I'm using 50% lower target FPS in AutoFPS as a workaround now.
