Hi everyone,
A few days ago, whenever I try to play apb I get very low fps for my specs, with gpu usage hovering around 18-20%. My specs are: Ryzen 5 1600 non OC 16gb ddr4 2400mhz Gtx 1070 8gb Apb on ssd Now here is the weird part: I've tried reinstalling apb and it fixed the problem, I got 70-80 fps on high, then on my next reboot, the problem came back. So ive noticed in a few games like mass effect and especially starcraft 2, ill have low frame rates and low gpu utilization, in the case of SC2, the FPs will drop to about 30fps, but the gpu will only be at 10-15% utilization.

Moreover my CPU and GPU usage in game are very poor (around 30 to 40%).

Low Fps Low Gpu Usage
My specs are :
AMD RYZEN 5 1600 3.2GHZ
Low Fps Low Gpu Usage Pubg
MSI B350M BAZOOKA16GB RAM 3200 MHZ
KFA2 RTX2060 SUPER
Low Gpu And Cpu Usage
Here's an example of my task manager with PREPAR3D open : https://ibb.co/C2KG0SMI would like to easily reach 25 to 30fps in the worst case if possible.

I'm running on PREPAR3D V4.5(dismiss my English level I'm French)
