Nearly double the VR FPS in FC3 vs FF?

I just bought FC3 today and was blown away. I had tuned my system to run 40-45 FPS max with drops to 30's in busy areas. DCS PD 1.3, MSAA 2x. I felt it was a good trade off of FPS vs shimmer/visuals. This was all done in full fidelity planes. Today I jumped in an F-15C for the first time after installing FC3 and immediately saw 90 FPS in open areas and solid 50-60 in congested areas with a few 45 FPS. I had no idea you could get 30-50% more FPS in FC3 planes in VR! Wow. Why is this?

System = 8700k + 2080ti

FC3 modules have no where near the 3D model (cockpit and external), shaders (cockpit especially) and system complexity.

F-5E runs 'fast' too for example, like a FC3 module. Mirage has pretty good performance too. F-18 and F-14 are performance hogs.

Yep, like Knock-Knock.

A lot of people are requesting super high resolution textures, super detailed 3D models (high poly count)...we pay it in VR fps, this is a trade off :(

At the current state of VR, we are limited by the hardware resources to run DCS even when it is oldest ones like Rift CV1.

Now go to highest resolution HMD models you can buy now 2019 and you will suffer even more. Why for most people it is best to get something like Rift S that will improve quality, but still maintain lower requirement for hardware specs to run it with most modules.

I actually get much better performance with my HP Reverb than I did with my CV1, because the CV1 required setting pixel density to 2.0 to even get close to what the Reverb can do at 1.0, and "close" was still really far away. I get a much clearer image, and the ghosting I used to experience with the CV1 is almost non-existent now. Win-win.

The number of pixels in the displays of your HMD, as it turns out, isn't nearly as much of a performance killer as having to use supersampling to get a semi-decent image out of a lower resolution display. With the Reverb, I use 100% SS in Steam VR, 1.0 PD in DCS, and the image clarity is amazing. In the first Red Flag mission where you're arriving at Nellis, with the CV1 I could see some kind of aircraft off each wing, one per side. With the Reverb, in that same mission, I can see 6+ aircraft off my wings, and even the most distant of those aircraft can clearly be identified as other A-10s.

Thanks, this is interesting.

Are you talking with the same hardware, or did you upgrade between the 2 (like RTX 2080Ti) ?

I have I7 7700K with water coolong, MSI GTX 1080Ti Gaming X 11 Go, 32 Go RAM and running on M2 SSD.

I'm wondering if my rig could handle the 2160p or if RTX 2080Ti is "mandatory" ?

Exactly the same hardware. No changes or tweaks of any kind were made when I started using the Reverb. In fact, I even did a side-by-side comparison last weekend, and had the same results I mentioned above. The performance was actually worse with the CV1, and that was because I had to crank the DCS PD up to 2.0 to make it look anything like the Reverb, and it still had a long way to go to reach the same level of clarity. All of that super-sampling/upconverting/downconverting stuff really taxes your system, a lot more than the higher native resolution does. I had always suspected that might be the case, but now I have confrimed it with my own observations and comparison. :)

Oh, and regarding the GPU needed. Back a few months before getting the Reverb, I upgraded from the 1080ti to the 2080ti, and to be perfectly honest, I really didn't see a significant improvement in performance. Although the 2080ti visual quality was better, giving an even greater sense of depth perception in VR. It was better, just not sure if it was $1500.00 better.

Thanks, because I'm not in the mood yet to swap my MSI GTX 1080 Ti Gaming X :D
