Low Fps Low Gpu Usage

Hi everyone,

Hello, As the title states, Ive spent months searching and trying different things/solutions and so far nothing worked, Im getting 150+ FPS in single player and under 100fps in online (60 or less in full public lobbies with 25 players or more) with low GPU usage, Ive started experiencing these FP. When the viewer isn't focused, you'll notice the FPS drops dramatically, it actually dramatically reduces activity when not the active window. SL does use the GPU a bit. I'm also using an RTX 2060 and when Firestorm is focused in ultra settings I see about 35% GPU usage (although my sim is more optimized than most as it's all made by me).


Since 1 month I upgrade my GTX 960 4GB to an RTX 2060 SUPER, I was exceeded of poor performances, but since I upgrade I can't see so much differences.
Moreover my CPU and GPU usage in game are very poor (around 30 to 40%).
With plane such as FSLABS A320 on airport like Paris Orly airport I barely reach 15fps... even with low settings.
My specs are :

Here's an example of my task manager with PREPAR3D open : https://ibb.co/C2KG0SMLow Fps Low Gpu Usage
I would like to easily reach 25 to 30fps in the worst case if possible.
