Disabling ASW (CTRL+Numpad1) does not stop ASW from capping to 45fps. It simply removes the extra added frames.
I see mine wander about 80 to 90 in menus but in the game it is capped down to 45fps and wanders down to 30fps in RES and Stations.
ASW is to make the frames more smoother and regular so it can then add the frames between. If it was jumping always between 45-90 then it would need to calculate each different half-frame and would be more process. When this figure is a known number it applies the added frame efficiently.
Unfortunately, it was intended to cater for slower systems but on most other than i7 it simply does not work with fast action 360 movement games (ED and Project Cars).
It therefore should have a Disable function in Oculus Home and also NOT cap all the fps to either just 45 or 90. We are being robbed our full potential. Although 45 is very good indeed. If only it was 45 for RES & Stations also!
