RealFlight Physics Speed

Hi all,

I'm currently doing some testing of using RealFlight as a simulation environment for research into reinforcement learning for aerobatic flight control of UAVs. However, there are a number of limitations that currently limit its use. The primary issue is one of speed. Currently, from what I can see, the physics engine can only be changed to run at 150% real-time. This is currently too slow for reinforcement learning use, with the need to run thousands of episodes.

Does anyone know of any way of running the physics faster than this? I think RealFlight/FlightAxis could be a really promising tool for my research if I could find a way of overcoming this.

The classic solutions are always available. While you cannot speed up time beyond 50%, you can MULTIPLY time via parallelizing the process.

Either set up multiple VMs or multiple machines, though both would be best. I just looked into the option, and it appears possible to increase the time factor of the VMs using VMware by enabling Accelerated 3-D.

Looks like VirtualBox has a feature called Warp Drive that will let you scale time as well. There was a problem reported 3 months ago with version 6.x, but 5.5 should still be available and functional for your purposes.

here you go my friend. i promise it isnt malware, if you want proof just tell me and ill send a recording of it working. its called cheat engine. just select the program (RF in your case) and then enable speed hack, from there you can change the physics speed from a massive range! (dont go too high or low as it will crash your sim if you do so!!) here:https://www.cheatengine.org/

Thank you, that looks like an interesting suggestion that could do what I want, although I am somewhat hesitant to use something that Windows Defender quarantines...

yeah i was the same. i usually test them on VM first incase it is malware, luckily this wasnt. it is a weird website too lol but it does the job. nad also, because it changes app data, windows defender considers it malware, although it is not
