April 7, 20233 yr FPS drops when starting engines ? And comes back when engines are OFF ? *Usually* this is due to the engine(s) having a kind of smoke or fake heatblur effect that kills your performance when the video card AntiAliasing is set to use "Transparency AntiAliasing" (which can bring FPS down to single digits even with a single 2D cloud on the screen 🙂 ). How's your video settings ? Can you check if your transparency AA is on and if the plane you use has a smoke effect or something like that ?

Sorry if it's a dumb question, but what is transparency AA? Can't find a setting named like that. I've: FXAA: Off AA: 2x MSAA TF: Anisotropic 2x TR: Medium - 1024x1024. Vsync:ON Triple Buffering: On Graphic settings are all medium/normal
April 7, 20233 yr I was referring to the settings in the NVidia Control Panel, in case you have an NVidia video card, of course. EDIT: you have a NVidia GTX 1070. So maybe you might want to take a look into the NVidia Control Panel to inspect your settings there. Another, maybe simpler thing to test, is to disable completely the AA in your sim, just for testing. Does the issue happen as well when AA is completely OFF ? If so, then it's not related to graphic settings. Edited April 7, 20233 yr by Daube
April 8, 20233 yr Author Problem solved!! When I set the fps limiter slider within P3d to unlimited, it was 144 before, the problem dissapeared. Thanks for your help, and for the fast replies!

Thanks for your help, and for the fast replies! From the help and advice I was given to a different FPS problem, if frame rates need to be controlled it works much better to have P3D's setting for that as "Unlimited" and use the graphics card's controller to set frame rate restrictions. Which you've already discovered! 😋
April 8, 20233 yr FWIW: I also see a significantly higher CPU usage with Aerosoft Buses and PMDG Boeing as soon as their engines are running.
