Made a better replica of Iracing hud, which i like very much. To use it, you have to manually start every widget in simhub and position how you want, then make it transparent.
It's actually optimized for rF2, but could try in the future to make it for other sims also.
The top right corner widget explained:
F=Gpu fan speed in %
M=Gpu memory usage in %
R=Ram usage in %
G=Gpu usage in %
C=Cpu usage in %
Installation: Just copy paste the files downloaded in simhub root folder and then start the layout from overlay studio in simhub
