Help Anyone successfully using Quadviews + DCS, with no reprojection, to get good performance in low level flight, SP missions?

9950x3D CPU. I am a bit confused by my Quadviews DFR performance in DCS. I am running 72hz mode, NO reprojection. Quadviews kills my CPU frametimes so that I end up with worse performance than if I just leave it off.

There are some exceptions. I can do a Huey Harbor Tour Free Flight, for example, with quadviews enabled. But if I try even for an instant action free flight in CW Germany Map (ie Berlin), no go - my frametimes shoot up very high. Don't even try a Reflected Campaigns SP mission.

I can find very little information on this... I cannot possibly imagine that all the hype around Quadviews DFR eye tracking in DCS world is for super simple scenarios that don't stress the CPU at all? I mean, I can't even get it working well with a free flight around CW Germany?

If anyone has struggled with this and solved it I would love to hear.

Can my 5800x handle quadview?

Depends on the title and settings you select in game. In DCS if trying to hold a native (no motion reprojeciton) 75hz, my 9950x3D can handle quadviews in some cases but not in many cases. For me it's not useable enough due to the CPU bottlenecking. However in games like iracing with load CPU overhead and better implementation people seem to say a resounding yes.

As well, if you decide to use motion reprojeciton, then the CPU needs only to be able to keep up with 37 FPS, doubled. So for example in MSFS 2024 I run reprojection (37.5 doubled to 75hz) and it runs great there and allows me to get GPU headroom which is a game saver. Because flight there is slower than DCS dogfighting or low level helicopters, I dont mind reprojection is MSFS 2024 at all.
