P3D 5.3 Hotfix 2 released

[brucewtb 247]

On other matters more directly related to the release of HF2 I note with apprehension that after 10 days or so since the release the F1 GTN 750 is yet to be made compatible.  I know it is EOL etc but we were hoping that these minor updates to P3D would be supported.

Yep, it works if you have the right hardware.  Been using it for the last 18 months in P3D.

Hi Bruce,

I held off on updating to HF2 for that very reason regarding the F1 GTN update for compatibility. Unfortunately I believe that minor F1 GTN 750 updates is a thing of the past. For that reason, I bit the bullet and purchased the RXP GTN 750. For me it was a very easy purchase, download and install. The panel configuration program is pretty easy to use. It will install the RXP GTN 750 where the  Flight1 750 is located. There are several helpful tutorials on the RXP support forum.

Hope this helps,

Raymie

The only thing is that I feel a sort of "ghosting" when limiting framerate from Nvidia CP, like a sort of artifact making movements a little bit slower than normal

I have this "problem" too...

It is the "approved" method for P3D for a long time now.

It's well worth the money, especially for the support alone.

If this method is "approved", it doesn't necessarily work as intended.

What should it do?  If I set my monitor to 60 Hz and vsync in NCP to 1/2 refresh rate (adaptive), while setting fps in P3D to unlimited and in-game vsync off, I should get a maximum frame rate of 30. However, on my system, I don't (I get 60 fps at most). What I described would work if you played a game that uses an exclusive fullscreen mode (like FSX did). P3D runs in windowed mode, even if you switch it to full screen. Judging by threads on this forum about this topic, many users also limit the fps to 30 in this case, whether in-game or externally. However, the 30 fps that they get is a result of limiting the fps to 30 and not of setting vsync to 1/2 refresh rate.

If the 1/2 refresh rate vsync worked the way I described, that would be new to me. Has P3Dv5 changed in this regard?  Anyone else can confirm that?

I have a G-Sync compatible monitor which I set at 60Hz and use NPI (Nvidia Profile Inspector) to limit the frame rate

to 1/2 refresh rate,ie. 30fps using the 'display port'. <important

This works perfectly for me with in game set at 'unlimited' fps.

My fps usually hover around 29 - 31fps.

But in your case, you are directly limiting your fps to 1/2 refresh rate by setting the fps to 30 in NPI. This is different from what I described above (=setting vsync to 1/2 refresh rate and running unlimited fps).

Right, I see what you're saying, give me a few mins and I'll try it with the limiter off and just 1/2 refresh on in NPI.......................

Ok, back to you now....

Removed frame limiter in NPI and FPS still achieving half refresh rate.

Tried 60Hz and 75Hz and FPS 30 and 38 respectively.

I know that P3D runs in frameless window mode but G-Sync will also run in full and window mode.

So it would appear that 1/2 refresh rate is working correctly

The Adaptive (half refresh rate) setting in Nvidia Control Panel requires VSync in P3D to be set to ON, at which point P3D will run at 30 fps.  You do not need to use the external frame limiter in NCP with this configuration.  As far as I know, this is not new to P3D, at least not the 64-bit versions, as I've run with this in both P3Dv4 and all revs of P3Dv5.

The FPS chart below is with this exact configuration, and outside of some scenery loading blips, it runs consistently at 30 fps.

In all the tests I have run, the most stable frames using adaptive vsync is with the P3D frame limiter set to unlocked.

Interesting, maybe the 1/2 refresh rate vsync in a windowed program is working for you because of the newer generation of video card, Gsync or simply a different behavior by v5. On my system with P3Dv4, it doesn't do anything, even if I activate vsync in P3D. In this regard, one last question: If you activate 1/2 refresh rate in NCP or NPI and run P3D, does your monitor run at 60 Hz or 30 Hz refresh rate?

It runs at 60Hz .

Well we will see. My only use these days for the GTN 750 is in the Realair Duke. That and the PMDG, FSlabs, Majestic etc stuff are the only aircraft I fly in P3D these days most of the time I'm over on MS2020,  I also still have P3D4 installed and the F1  GTN 750 still works there.  I was using it in the Lionheart Kodiak but no more as we now have the excellent Simworks Studios Kodiak in MSFS 2020.
