i do not understand, I am using my oculus CV1 without any plug in, what am I missing, what should I do to get better performance?
I am assuming we are talking FPS here, not sharper image. PM me please if this feels like OT.
I'm guessing you've never used RHM?
In VR it's useful because it lets you balance visual cockpit and environment movement (mostly up/down oscillations as you drive along a bumpy road) so you can have degrees of each set to personal preference.
The AC 'lock to horizon' defaults to on or off, but RHM effectively lets you tweak along sliding scales so you can have a little bit of cockpit shake and a little bit of environment movement to emulate better what we see in real life.
LTH can also feel weird in VR when going up and down hills. RHM cures that.
Our vision is naturally great at filtering shake and vibration IRL but not in our VR displays.
With 'lock to horizon' ON, the road will be perfectly stable and cockpit will move around a lot.
With 'lock to horizon' OFF, the cockpit will be perfectly stable and road will move up and down a lot.
RHM lets you fine tune this and have both effects on and tweakable.
IMO RTM is leagues better than LTH, but has always been a CPU hog. This new version for ACC (that works fine with AC) is a lot more optimised and uses a fraction of the CPU cycles, so will improve overall performance a little.
Just remember to disable LTH if you use RHM.
I use RHM in VR with the default settings. I find it makes the image more stable (and clearer as a result) because the road ahead (and other cars) isn't shaking up and down all the time unnaturally like it does with LTH disabled.
Also, what I said in an earlier post:
It seems you can also rename the ACC RHM executable to RealHeadMotionAssettoCorsa.exe which allows CM integration for auto-launching.
This isn't necessary, just change filter in popup dialog to "*.exe" so you can choose any executable, same applies to RHM settings file location dialog (*.xml)
Thanks to Andrew_WOT for the tip.
