To answer my own question.
Go to youtube and type in performance vega or 1080ti. You will see one consistent think, both the 1080ti and the VEGA will be running at ~ 35% capacity with FPS 30-55 favoring the 1080ti. I typed that correctly, the utilization of the GPU is only about 35% with CPU utilization about 20-30%. This is a problem with XP11 coding since both brands are way under preforming. check out this comparison of 1080 and vega 64. https://youtu.be/CSaAe6_gJ-k
Notice the vega has a lower FPS but look at the utilization. There is a ton of examples like this.
A very long story short, I just completed testing xp 11.20 beta with my system and found some very interesting results. If I turned everything down with the default Cessna or 747, resolution 1280x786, lowest visual effect, texture quality, world objection , reflections....everything, the FPS was 67 with GPU utilization of 60%, Vram 20%, CPU 21% (no cores even close to max), Ram 17%. After running literally running 30 different scenario (I kept track of every combination in excel), the best combination of appearance to utilization was FPS 40, GPU utilization ~65%, Vram 48%, CPU 15%, Ram 24%, with setting of: Resolution 2560x1440 Visual effects high (hdr), texture maximum, Antialiase 4x SSAA, number of world object Low - medium, refection minimal, draw parked aircraft on, flight models per frame 2. Of note, the problem I was having above is that I had the flight models per frame up to 10. If though it was not even coming close to pushing my CPU utilization > 25%, it was killing my FPS without using my GPU. I don't know why this is. Where is the bottle neck?
When flying a payware, Mooney M20, the FPS dropped but with less utilization so the setting changed to: Resolution 2560x1440 Visual effects Maximum, texture maximum, Antialiase FXAA, number of world object medium, refection minimal, draw parked aircraft on, flight models per frame 3. with FPS of ~ 33. This looks gorgeous!
In summary. It is really frustrating to buy such hardware and see it mostly idle. XP 11 is a poor use of resources for the Vega 64, 1080, 1080ti.
I really hope the Laminar crew and code this better.
