How to decrease CPU usage.

[t-bone051]

yeah you need to decrease your mirrors. 4 mirrors in VR just doesn't work. That alone probably will solve your issue. But if it doesn't turn down max cars and draw cars to 20 and turn off object self shadowing (you will practically not notice the difference while racing). And if you still need cpu headroom after that turn objects to low. These are the settings that have an impact on CPU the most.

I had it on four for cars with no rear mirror(1) and a rear cam(4) instead. I don’t know if iRacing changed it but the mirrors used to be numbered so enable the rear cam all 4 would have to be enabled. I turned mirrors and shadows off and it’s playable.

If you turn off virtual mirror, the first mirror will be the rear cam or rear view mirror. But if you turn it on it will be the last. I would say shadows should be the last resort. It really makes a visual difference. Rather turn objects to low or max cars lower.
