RTSS and P3D

You can also set an fps limit in the Nvidia Control Panel, Manage 3D settings, Program Settings, Prepar3D.exe profile. Restore/Apply first and make just the fps limit to 28 and apply, close NCP. In P3D display settings, set Unlimited fps on the slider and set VSYNC=Off. You should see the fps wobble around 25 to 35.

With regard to blurry textures, this indicates a slowness in collecting and rendering scenery textures.  Start with low scenery settings, see if the blurries are gone, and if so gradually increase scenery settings.

Is the fps wobble to be expected in this scenario? I see this any time I try to apply a FPS limit outside P3D (I am on and AMD GPU, not nVIDIA).

Yes. When you use the internal P3D Display Setting fps slider it is not actually a limit, instead it displays each frame (if a frame is ready in the look ahead buffer) after a set time period determined by the slider.

Interesting - thanks. I seem to see this however I limit frames. At first I thought maybe my system couldn't maintain the say 30 fps, but it does it wherever I limit them - say even at 20 fps or 24 fps.

External limiters will try to cap the framerate but frames take different times to complete making the actual reading inconsistent. The internal frame rate target slider will produce very consistent times between frames assuming there are frames available in the look-ahead buffer.

Yes, on AMD we are kind of limited and so it is either the internal limiter or Radeon Chill where you set a minimum and maximum FPS. Thanks for the very helpful explanation.

Hi Steve, do you use RTSS? I'm also trying to figure out what works well like OP, so I've tried setting Scanline Sync x/2 to 60 and capping frames to 35 in NCP. Do you recommend something else?

Best wishes!

Set your monitor refresh rate to 60htz 

and use scan line x/2  smooth as butter 

with P3d and msfs now

cheers

I have now found that the newer NVControl Panel does away with the need for RTSS. On my system it is possibly slightly smoother as well.

Hi Mike, do you use an fps limiter?

I just flew to LGSM and get 50 fps without a limiter, but setting scanline x/2 to 60 and fps limiter to 30 gives me a bunch of stutters when turning the aircraft on the ground, which seems weird given I can get more fps than 30.

Do you have any ideas?

Lower your settings.

start at a dense airport like klax and lower your settings to maintain 30fps.

and your good to go.

I've been getting decent results but when I cap frames to 30 in Nvidia and use application controlled VSYNC (also VSYNC is off in P3D), I get some screentearing when using RTSS. What VSYNC settings do you recommend?
