Since SU9, I’ve had overall slightly better FPS and smoothness, ie better frametiming.
However, this only holds true while stationary or at altitudes of around 1000ft+.
Especially in areas with buildings, when im flying at 0-800 feet or so and look out the side, scenery moves past with extreme stutters,while still maintaining my locked-to 45fps. As I climb through 1000 feet, it becomes smoother again. This is NOT just an effect of the decreased perceived speed as I climb, it’s a night and day difference.
I get a similar effect but only where i have addons etc. Firstly, I use motion reprojection and fix my frame rate to 23 but 22.5 in the OpenXR Toolkit where I am running at 95% resolution so that’s pushing my 3080. This allows me to see amazing detail in my G2 and fly low and fast over the countryside. However, if i try to land at London City, for example, it stutters big time and i have to reset everything. So, i just fly around avoiding areas where i have addons.
Addons such as London City airport or Great Britain Central. You need to try Motion Reprojection plus OpenXR Toolkit. Recently, I’ve been influenced by Crash Test Pilot’s YouTube video. It’s a game changer.
Are you using any external fps-limiting software? I have experienced microstuttering with driver fps limiter and other fps limiters. I have switched to using the in-game Vsync/limiter only.
Yes, I usually lock to 45FPS with Rivatuner. I don’t think it makes a difference but will try again, thanks for the tip. Does the ingame vsync even afect VR though? Since it’s in the PC section…
Good question, I don’t know. Flight Simulator is the only game where I’ve noticed this frame-pacing issue caused by external limiters. It might just be my setup.
On my setup the Nvidia setting was almost completely fluid. My frame-time graphs showed smooth lines without any spikes, but there was still visible microstuttering when flying over buildings in photogrammetry area at low altitude.
Was your head motion smooth? This is the part I don’t get - even when I get extreme scenery stuttering, the head motion still feels completely smooth, as if only the scenery motion is affected by the stuttering. How is this possible?
I’m not sure, but it seems logical in my case, since external FPS limiters insert themselves into the CPU side of the rendering process. Whereas the simulator’s built-in limiter is more on the GPU side, being directly dependent on the display’s refresh rate.
Not too sure about that. When displaying the FPS meter when limited using nvidia, the GPU shows a very solid 33ms render time, while the CPU is around 20ms.
) so it at least used to work.
