Default 2080Ti and VR Benefits

So I did some testing today with the latest beta patch. I wanted to check out the new P51D textures. So I flew the P51D Instant Take off mission in NTTR. I flew ground level through downtown Vegas.


In FA18 Take in PG Map. Instant action missions Take off & VFR Landing. Also flew at ground level through downtown.


The picture is terrible because I had the Rift on and wanted to take it while in VR (Pic of the desktop).


And I got pretty much solid 45FPS. It might have dropped off to 38 for a second here and there. But almost always at 45FPS. I believe I turned on all the things that eat FPS (shadows, SS/PD 1.8/MSAA 4X) and it was just fine at 45FPS. Anyway, just wanted to provide another data point.



Settings were
Oculus Tray Tool. Super sampling 1.8. ASW Off.


DCS Settings:
Terrain HIGH
Texture HIGH
Water Med
Vis Range HIGH
Heat blur Low
Shadows HIGH
Res of Cockpit 1024
MSAA 4X
Depth of field OFF
Lens Effect None
Blur and SSAA OFF


Slide bars, you can sorta see. Tree and Grass were maxed out
Anistropic 2X
Terrain Obj Shadows Default
Cockpit Illum On

What CPU and what clock speed?

VR is historically CPU bound, so that will go a long to to interpreting these results. What GPU Core Load % were you holding while flying? What did it drop to (or did it not drop?) when you saw the FPS come down to the 30’s briefly?

Thanks for the results and enjoy the new card man!

Also, it’s best to bench in a premade mission with a ton of units on the ground. VR becomes a problem when unit count goes up (like MP or elaborate SP missions), so that’s where you’ll want to see how it’s performing.

I can try a mission if there's one for me to download. HW Spec in .sig, and it dropped for a second to 38.

However, when I landed in the FA18 BFR mission in NTTR (I think it was), I went into the concourse area of LAS airport. By where the 727's were hanging out. And as I taxied in between the commercial jets, the FPS dropped to 28.

I'm going to do some more testing. I use Instant Action because everyone will have a the frame of reference.

If anyone wants to give it a shot and post the FPS, maybe we can get some comparison going. It will help those shopping for VR/GPU/CPU.
I'll see if I can get more detail via third party software on GPU/CPU usage. But no promises since I have a new CNC to play with LOL.

Don't think its just a 2080Ti benefit. I've noticed significant improvemenst in Caucaus F18 free flight through the valleys with maxed out MSSA, SSA and anisitropic filtering hitting mostly 45fps whereas before 2.5.4 things would be at a crawl.

I've tried that in the past, maybe two updates ago?, and I didn't really have any issues with maintaining 45FPS. Even when I had the 1080Ti. The only one that caused issues, this is a while ago, was the CAS Insant Machine in Normandy. It's gotten progressively better where maintaining 45FPS was doable. It would dip to high 30's though. I'm going to test that next.

Try the 'Sitting on the Ramp' Hornet Persian Gulf Mission. Look at the (horrible) fps immediately, go to runway, look to the left at the other parked hornets (see the drop?), take off, fly to 300, go to sea, then turn and fly over all the populated areas at low altitude, rolling 45 degrees left and right.
That is the real test!

Will give it a shot today/tomorrow. Yesterday, I tried everything I mentioned above using 1.2PD. Saw no difference. I'll give 2.0 PD a whirl. I'm glad it's performing well at 1.8 since I expect my Pimax 5K+ in a month or two or three

Did the Ready on the Ramp, PG. Without shadows, solid 45 to 90FPS.



I did your route. look at the parked FA18s, Went to the sea, over the containers, over the palm island. jinked towards Burj Khalifa, came back, made a left to the air strip and landed.



With shadows on HIGH/DEFAULT, 28 FPS when looking at the other planes.
Solid 45 to the see, over the containers. At see, hit 90. But then when you start jinking left and right, the shadows sweep across the cockpit. And the FPS drops to mid to high 30's then settles down to 45 when the shadows stop moving around.



I'm going t download FCAPS VR from NVidia and see how many frames are getting dropped.


The above is all with PD of 2.0 (up from 1.8 of my original test). ASW is default.
