I set Prepar3D to only use 10 out of 12 of my logical processors, when P3D is loading I get around 80% CPU usage but when I get into the actual simulation the usage plummets to around 20% - 40% and doesn't go any higher. I tried making P3D use all cores, little to no difference. I know it most likely isn't a bottleneck of any kind since previously I've had P3D V4 run on all cores at 100% CPU usage with fine temperatures and high framerates, only recently it's started doing this. Specs: i7-8700k GTX 1060 6GB 16GB DDR4 3000MHz 250GB SSD When P3D is in the simulation: As I said earlier, it can't be a bottleneck since it's been running at 100% before with all cores being used. Doesn't even do that with all cores checked now.

Hi all, I was wondering if someone could help me. I'm getting really poor performance issues (Low FPS and huge micro stutters) in Prepar3D v4.1 with Dynamic Lighting enabled. I have tried the following things, but there are still many issues. I have tried a range of aircraft in which some struggle more than others. My system is: Intel Core i7 4770K (OC'd to 4.3 GHz) CPU, ASUS GTX 1080 Graphics Card, ASUS Z87-A Mainboard, 32 GB Corsair RAM, Samsung EVO SSD, Hisense 4K TV (40 inch). The following aircraft are: PMDG 737 (600/700/800/900) - Mild stutters and low FPS when external lights cross each other, also when dome light is enabled. PMDG 777 (200/300) - Mild stutters and low FPS when external lights are switched on. FSLabs A320 X - Bad stutters and very low FPS when FS Spotlights is enabled in the cabin. Some mild stutters when external lights are switched on. Majestic Dash 8 Q400 - No issues (Assume this is because it still uses legacy lighting? When Dynamic Lighting is switched off, lights can still illuminate the runway). Aerosoft CRJ X - Bad stutters and low FPS when Flood LT dial is switched to on and flood lights illuminate the flight deck. I have tried the following things: 1. Set exclusions from Windows Defender for the Prepar3D v4.1 folder, FSLabs folders etc. (as advised by FSLabs). 2. Changed resolution from 3840 x 2160 to lower resolutions. 3. Deleted all shaders and started with a Vanilla Copy of Prepar3D v4.1 with no addons apart from the particular aircraft. 4. Updated/Downgraded Nvidia Graphics Drivers. 5. Upgraded aircraft to the latest version. 6. Formatted my PC and ensured that everything is perfectly working. 7. Configured my Nvidia GTX 1080 on High Performance and kept all P3D settings to a minimum. 8. Changed TV Monitor from 60Hz to 30Hz and configured with/without V-Sync etc. 9. Changed all AA settings (FXAA, MSAA, SSAA, SGSS). Any help would be greatly appreciated. Does anybody have any ideas? I assume this is a genuine issue and something that will be resolved in the future? Many thanks, Pete
