PC GPU memory clock in SimplePlanes...

so... I've managed to isolate the issue with SP and horrible performance despite me having a beast of a laptop.
The issue is as follows, SP DOES NOT use GPU memory clock, in fact, memory clock stays at idle all the time, which hinders the perfomance significantly.
as reference, my GPU, has a processor clock of 1366Mhz and Memory clock of 2000Mhz, SP mantains the memory clock at 300Mhz. you can see this reflected in my GPU temps, I barely reach 28°C, whether as with demanding titles I have my GPU at full capacity and reaching temps of 55°C and the fans at 90% throttle.
here you can see my GPU barely making an effort

Meanwhile my pc is struggling to run a WIP +1000 parts engine...

    @Kennneth I know that for today's standards, it is highly outpaced... but this 3rd gen I7 is on par or better than a 2nd gen desktop I7... take into account I've been running this laptop since 2015 or earlier. and desktop I7's LGA15xx didn't get an upgrade in core count until 6-7nth gen. It is nontheless a 4C/8T CPU running at 3.2Ghz nonstop

    the CPU is what calculates the parts on your place, and that third-gen i7 is anything but a beast... @marcox43

    @SodiumIodide laptop Samsung Series 7 chronos 2013: I7 3635QM, 12GB RAM DDR3, 1TB SSD, External GPU XFX OC edition Radeon RX 580 8GB and two screens at 1920x1080p

    I have the same issue. GTX 1070ti, Ryzen 7 2700 and 32gb of DDR4 3200Mhz RAM should be enough. Yet the game still drops to 30fps with 1000 part builds.
