Most wanted in P3D V....

I guess we disagree ... threads have to be instantiated and that which instantiates much manager, hence C++ thread manager class.

A bit of a simplification, they probably use a library or c++ ThreadPool rather than direct thread creation and join (which is trivial).. anyway, kind of off topic, the engine could use multi cores much better, I hope for a big improvement in v5.

Dawn/Dusk doesn't impact my FPS, that will only happen if you either run out of VRAM or you're using some additional shadow tweaks via manual changes to the prepar3d.cfg.

Interesting, I do not use any tweaks other than extending tree draw distance (for night lights) but I am using TomatoShade so will do some more testing. 

Dawn dusk performance seems to be a fairly common issue online.

I'm using PTA but no issues at dawn/dusk with no shadow tweaks ... shader modifications can potentially impact performance.

The latest Windows 10 builds and P3D V4.5 HF2 have been extremely good with performance ... my hunch is one of the MS OS updates (build 10.0.18362.387) fixed an issue that seems to have really helped out P3D.

Cheers, Rob.

Cool, I guess it is time to finally man up and bite the bullet on installing HF2 😬

Incidentally, how did you lock your frame rate to 30FPS but still use Unlimited?

Didn't you suggest in one of your former videos not to use "unlimited" VSync @ 30 Hz because of disappearing autogen?

Hello, 

Improved ATC control, improved airport ground control

Maybe because I am using HDMI + TV but that does not limit my P3D frame rate to 30 even when I set display adapter to 30Hz sadly.

I can confirm the Cloud Shadow Dawn Dusk bug is P3D and not tweak or custom shader related. I let P3D rebuild Prepar3D.cfg, no tweaks, cleared shaders, no Addons, no scenery, all minimum GFX settings except Cloud Shadows ON, god its fugly, CPU between 5/12% flying a Cessna across Chicago Westwards locked at 60s FPS but could probably do 200s FPS+

Change time to Dusk and the framerate dies to 10FPS with 100% GPU on 2080TI and min GFX. Rotate view away from the sun and its is back to 60FPS, GPU load reduces.

LM if you are reading, please fix this bug in V5! I love flying at Dawn Dusk but its unusable with Cloud shadows, I now have tp have a SimStarter config just for Dawn Dusk flights 🤦‍♂️
