P3D V4.1 Insane FPS drop


Recommended Posts

Hello guys,


I´m writing this beacuse I can´t figure this out. I Installed my p3d v4.1 and it worked fine for a few days. However in the past weeks my FPS drops from 35/37 to 21/22 and then to 8/6 making tha sim almost impossible to use. I´ve tryed to reinstall everything, reboot, even a complete reinstal of my OS. This started to happend from nowhere. Can anyone have some clue about what is happenng?

Here follows my specs and P3D settings:

-Intel I7 4770 3.4Ghz


-AMD R9 270 2GB

One more thing, my GPU is at 99% and my CPU is at 12/13%

That said, I'd say your biggest bottleneck is the video card. It just meets minimum system requirements for P3Dv4 (see below copied from the P3D site with color added) and some of your sliders are rather far to the right for minimum specs. I don't know why you were getting better results initially, but for sure try moving the sliders to the left until you get decent frame rates, then experiment with moving the ones most important to you a click to the right.
