In P3Dv5, the DX12 implementation generates regular OOM when some graphic options are checked and saturate the video card. It is probable that they work implementing it better in FS20 to avoid this.

P3Dv5 is not full DX12 api. It still has quite a bit of ESP code.

One being bottle-necked by the IPC and Ghz of ones processor. Everyone is. DX11 is limited in it’s multi-threading capability and just generate too many draw calls that exceed any CPU in existence today. Even if it scaled to other threads, the main-thread is really the cause of your lower GPU usage. It is the case in P3D, XP11 and FSX. This has always been the #1 reason why frames are always lower in flight sim. You would think that P3D, as being a DX12 application (not full), would fair better but the legacy ESP engine code is still way to single threaded focus. It’s very easy to see. Load a PMDG 777 in P3D. The frame will vary to 40-50FPS. Pause the sim and your frame will jump by almost 80%. This is because simulation code and draw-calls are on the same thread and limited your CPU to drive your GPU.

This is not rocket science. Asobo needs to port their engine to a proper DX12 engine. (not like LM did) and implement DLSS. This is the only way we will ever get 60 fps in this sim. A RTX 3000 series will not help us. We need lower draw calls or spread the load across enough thread that it doesn’t bottleneck the GPU. When you increase the render scale, all you are doing in loading higher resolution to your GPU (just like DSR), it doesn’t provide you more frames.

A true story and my computer is a low high end. High settings. With GA Aircrafts around 40-50fps. In LAX down to 30. With 787 about 20fps.

A lot sutters too depends on the area i am flying.

Cpu and Gpu running around 50-60%. The Gpu(Rtx 2060 super) is running hot all the time(80°C)
