Tobias94 33 Posted February 7, 2018 Share Posted February 7, 2018 Hey guys! I am still pretty much appreciating @Jo Erlend Trondheim scenery However I noticed some serious FPS issues with Dynamic Lighting on this specific scenery. These problems only occour at night and only when I have a look on the terminal area. Trondheim is the only airport where I have such FPS problems with the dyn. light. My scenery version is 1.02, P3D v4.1. System: Intel i5-3570K @4Ghz, 16GB RAM, 6GB MSI NVIDIA GTX1060 Gaming X, Windows 10 Link to comment Share on other sites More sharing options...
f.skywalker 17 Posted February 7, 2018 Share Posted February 7, 2018 Turn your Grafik Settings in the night to 2xSSAA This helps Frank from EDDM Link to comment Share on other sites More sharing options...

I also doesn't do any change when I switch to another AA setting or even if I switch it off. I still get the FPS problems then. Link to comment Share on other sites More sharing options...

It won't help much! Any SSAA mode in P3D4 will still affect FPS with dynamic lighting on and performance will suffer. A known issue in P3D4. You need to set the slider to 8x or 4x MSAA. Do not use SSAA at night, especially because the 1060 is not the strongest video card. I have a 1080 TI GTX, and have a night setting for night flights using 8x MSAA and one for day flights using 2 x SSAA. Maybe if the new Volta comes out this year, users can use SSAA modes wit lots of dynamic lights. Link to comment Share on other sites More sharing options...

I can turn AA completely off, but still got the same FPS problems. The only way these drops stop, is turning off Dynamic light Link to comment Share on other sites More sharing options...
Cargostorm 98 Posted February 7, 2018 Share Posted February 7, 2018 I see, our posts overlapped since we posted at the same time.... Have you tried to delete your shaders cache to see whether it helps with dynamic lighting? You find it at Local Disk (C:) ► Users ► You ► AppData ► Local ► Lockheed Martin ► Prepar3D V4► Shaders You can delete it. It needs some time to rebuild if you start the sim.

Aerosoft Aerosoft Team [Inactive Account] 51558 Posted February 8, 2018 Aerosoft Share Posted February 8, 2018 Dynamic lights are calculated all the time and thus depend heavily on your GPU. In P3D v4 they will never be fast due to the rendering system. Link to comment Share on other sites More sharing options...

Also my GPU is bored during flightsim. The GPU workload is only at about 45-50%, checked with GPU-Z. Again, this problem only appears when the Terminal is within the field of view and only in Trondheim. No problems with Oslo, any German Airport, London, etc...

Aerosoft Aerosoft Team [Inactive Account] 51558 Posted February 8, 2018 Aerosoft Share Posted February 8, 2018 I can't explain that, I see no specifically low fps with that airport. The overall load of the GPU is not too important btw, it's the speed at which one process is handled. Link to comment Share on other sites More sharing options...
Tobias94 33 Posted February 8, 2018 Author Share Posted February 8, 2018 Pretty unsattisfying... Locked 30FPS during taxi when the Terminal and the dynamic flood lights are out of sight - and a drop to 10-15FPS during approach and all situations where the Terminal and the flood lights are in sight... So, if the GPU would be the issue or bottleneck, TRD wouldn't be the only airport where problems occur. EDIT: That should be clear, but these drops of course only at night/dawn when the the dyn. Light is active. During the day, everything is fine and smooth. Link to comment Share on other sites More sharing options...

The performance increase only happens when I tick off the Dynamic Light in the P3D settings. It is quite similar for me, to the issue sceneries like Stuttgart had in the beginning. With Dynamic Light 10-15 FPS, without everything is fine. Link to comment Share on other sites More sharing options...
Aerosoft Aerosoft Team [Inactive Account] 51558 Posted February 9, 2018 Aerosoft Share Posted February 9, 2018 But as far as I know Stuttgart had no tweaks to the lighting. Link to comment Share on other sites More sharing options...
Developer Jo Erlend 2144 Posted February 13, 2018 Developer Share Posted February 13, 2018 Hi @Tobias94, try and replace the old fx files for Trondheim with the ones included in this zip, let me know if this improves the performance. Extract the zip file and copy the three .fx files into "...\Prepar3D v4\Effects". (Remember to make a backup of the old files just in case.)
