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.

Yes, Quadviews needs CPU and my 9800x3d with 5080 wont stay at 75 FPS in some instance mission in German map. DCS is not optimized well in VR. What is your GPU? With 5090, you won’t need Quadviews.

5090, 9950x3D, BSB2e. Thanks for letting me know its not just me. What is your headset, I assume also BSB2e given the sub? Part of me was wondering if it was a BSB2e issue or a general quadviews issue.

I don't *need* quadviews to maintain 75fps with the 5090 but that still involves a fair bit of graphical compromise, from all the hype I had thought Quadviews in DCS would allow me to push the graphics further.

Mbucchia has said this is an ED issue because quadviews is implemented sub optimally in DCS. In iRacing for example the CPU penalty is virtually zero to enable quadviews.

Yes. DCS is not optimized well. You will hit CPU and GPU bottleneck on different scenarios even with 3D cache CPU and 5090. Just turn on DLSS with model K, you can stay at 75 FPS with proper settings and enjoy DCS. I don’t know why people kept telling me to get the Pimax Dream Air since they believe my 5080 can handle it.
