[RESOLVED] P3D v4.2 G-Sync not working...

[chris512]

Hi,

Has anyone got G-Sync working with P3D v4.2? I saw it work once, then it stopped and hasn't worked since.

I've tried reinstalling my nVidia Driver. (397.64) I've also tried setting it to "Enable G-Sync for Full Screen mode" and also "Windowed Mode" neither seem to work. I'm watching the built in frame counter on my Asus Screen, it does show G-Sync working with X-Plane, so I know the Screen Counter is working.

I'm running the latest Windows 10 Spring Creators Update. (Version 1803) OS Build 17134.48.

Can someone help me please?

A bit of progress... I did a clean install of the nVidia Drivers by using the tool available on this thread.

G-Sync works for the first run. Then after restarting WIndows 10, it stops working...

I had a similar issue once, try and disable windows fast boot and see if that helps.

OK thanks, I'll give that a go...

After an evening spent trying to get this to work I've discovered the following:

If I do a clean install of the nVidia Driver (397.64), restart and run P3D, it works. Smooth as butter, even with the FS Labs and Dynamic Lighitng. Glorious! If I then close and restart P3D, it still works... If I restart Windows 10 and then run P3D it won't work. I have to do a clean install of the nVidia Driver again. I'd tried this cycle 3 times now and it happens every time. If I run X-Plane, the G-Sync works whatever I do. So this is just a P3D issue so far. I really don't want to have to do this every time I want to use P3D! It's unusable without G-Sync for me.

Changing Fast Boot to Off didn't work... Thanks anyway. I hope someone at Lockheed Martin will be able to help. My G-Sync is stuck at the full refresh again now, until I go through the process outlined above again...

I wonder how you manage to have your settings as such as G-Sync makes any difference... I know I tend to rather high settings, but as G-Sync only works from 30FPS upwards, I turned it off for P3D anyway. I don't want to lower my settings that much that my FPS are constantly above 30FPS... And if the FPS are fluctuating between FPS above and below 30, my G-Sync monitor flickers visibly. Not nice to see...

Is there someone from Lockheed Martin that could help me with this please? I've reached the end of my knowledge now...

I did this and it works without G-SYNC without any problems at 50 fps

The ideea, i belive is that you should not give much work to the processor and graphic card that is why i say that you sould block the framerate to 100 from P3D if you are running a 100 Hz monitor then block it to 50 from Riva tuner (it's half refresh rate), or if your running a 60 Hz monitor block to 60 in P3d and at 30 in riva tuner. I don't know exactly what is the catch but it works (if u set half refresh rate in Nvidia inspector). Maybe is Bullsh.t what i'm saying but it worked on 2 computers.

... and definitely you should use "SIMstarter NG" from aerosoft, the app is doung magic in stopping programs what you don't need when you fly. Try it.

Thanks for the suggestions guys. I'll give them a shot. I would like to get this G-Sync issue solved though. It's really great when it works, and I paid a fortune for my G-Sync screen!

Coming at this from a different angle (I was researching the G-Sync issue elsewhere as it might not be P3D-related), someone mentioned terminating the dwm.exe process (desktop). It restarts immediately and this might help your G-Sync issue even after you have rebooted Win 10. I would close any display-sensitive apps before doing so.

I solved this problem in the short term by downgrading to Windows 8.1...

How's that for progress...
