I believe 5.3 HF2 is where the performance improvements really shine, but apparently there are some visual bugs that still need to be worked out that I haven't been able to as of late.
I decided to move from P3D to X-Plane 11, it run much better on my laptop. I also tried the XP12 but due to my gpu only have 4gb of vram, i'm only getting around 20-30fps
