VR FPS (2.5.1.16543.355)

I don't understand how you guys are getting such bad fps. I have an old i7 3770k, 16GM RAM, a 970 and run on a SSD. I get between 45-90 fps all the time. I barely ever see it drop under 45. I have most tings set to High. MSAA off and AF set to 2x. Pixel Density I change depending on what I am flying. If I had a newer i7 and better graphics card like most of you I would assume I would get much better.

Wooooow just bought an RX 580 8 GB, these are my results (caucasus)...

in singleplayer I only get 17-23 fps when I start "M2000 missile combat", in multiplayer 14-17 fps on ramp (when M2000 warmed up) and 12 fps flying Mach 1 low over Krasnodar, using the settings you see in the 2 screenshots here

Terrible. Needs optimization ASAP (or Vulkan API).

VR Preset, then Lower Visibility Distance, as well as MSAA OFF, AF 2 Maybe 4x. Pixel Density less than 1.2 for that GPU.

Does "Visib Range" include mountains, clouds, contrails from aircraft?

Hmmm with VR preset I now have around 27 fps in multiplayer (but no mountains on horizon... -.- :P I'll just imagine that there is distance fog I guess... But hope ED can add low LOD mountains to medium "Visib Range" setting too, soon.)

But there is insane flickering around the autopilot buttons now (using VR preset). is this due to MSAA off or due to low Anisotropic filtering setting?

And.......WHAT to think when VULCAN API is integrated. :D

 

 

FPS boost ~30 - 40 %

yeah, Vulkan, good look with that.

Look or luck? You sound sceptical about Vulkan...

Vulkan is not a silver bullet that can fix all our problems. People are seeing a massive drop in the performance on Nvidia's graphics cards compared to Directx11 and this with a "highly optimized" engine. Vulkan is a much more complicated and difficult to work with than directx11, so I don't know how they will do it with their limited resources. At best with Vulkan, someone will see a 30% increase in performance but most of us will be ****ed. If this were my decision, I will try to optimize the current engine, I think it should be easy to see a 30-40% improvement in performance with the current engine if they are willing to optimize the VR. A different story is that they may not give a shit about VR since it's a niche market and they don't have enough resources to improve it (this is confirmed to me when they removed the Forward rendering option).

2.5.2 (.17559.377) has no improvement in performance.

The new update has almost identical performance with previous versions (well within the measurements uncertainty).

The new Anti-aliasing method present in the settings (SSAA) is not compatible with VR as it produces distorted view.

It is more or less identical in operation with the Pixel Density setting so it is no big deal.

The brown curve (2.5.2 SSAA) is pretty pointless (especially in conjunction with PD other than 1) but included just for fun.

Still SAD...

PS I got tired and frustrated so I skipped the 1.8 PD settings. In any case the trend of the curve is obvious.

From my limited testing, I come to the same conclusions :(.

Your opinion on 2.5.2.17978.385?

It got alot worse for me on the latest OB patch.

Your opinion on 2.5.2.17978.385?

Hi Hippo.

Still sad.

The latest measurements are attached below. Identical performance plus I see some serious spikes every 5 to 10 seconds that were not there before.

So, very very sad to be honest. I cannot play the Hornet on 2.5.0. My days of 90 fps in DCS with great (for VR standards) graphics are coming to an end.

I have lost interest in keeping my servers up to be honest.

I want to fly the Hornet and I see the jaggies and the low fps and the BAD quality and the unreadable gauges and the carrier that I can hardly make out and I get very sad.

Oh well, life's got so many other good things... No need to spend my time on this.

Cheers !!

Any official quote / response from ED regarding frame rate issues?

I get like 35 fps in VR with mostly high settings according to the windows wmr dev portal. I've been mostly flying the hornet. But I don't know if that is accurate as tracking is smooth and no stutters or jitters.

Why are you running PD and SSAA at the same time?

I am not. It was left there from previous test :

I will correct the table as to not confuse people.

Thanks for spotting it.

Not that I know of.

And certainly not to me... LOL

Sorry to hear - thanks for posting your results though.

.... and I get very sad.

Unfortunately this has been my experience with DCS for the past 15 years....

It has just always held that stigma of a very poorly optimised flight sim, while the sim by itself was amazing... it just always frustrated you with the poor optimisations graphically so was left un-played for 6-12+ hoping for improvement.

Have just come back after yet another break due to the F-14 getting closer so need to brush up on my piloting in the F-5 after waiting for 2.5 to sort itself out and hopefully VR support to mature.

No such luck - in fact the performance in VR it is actually worse now than when I left as you have shown. Granted I am attempting to play in VR which I guess is still 'new tech'.

If I went back to a flat screen with my 1080ti I am sure I would have great performance....but then it wouldn't get played anyway due to no VR.

I am actually a little concerned that when the F-14 and carrier get released this move towards DS etc. forcing VR players to minimise their settings, run at PD 1.0 etc will mean the picture quality will be so bad in VR you won't even be able to make out the meatball :doh:

I can only hope the focus moves away from the ability to make pretty screenshots in 2D mode to some more consideration of the future of flight sims being in VR.

Why don't you go into the options and changed Deferred Shading from a 1 to a 0?

And that works does it?

Hate to be negative on the OP, but from a point of view of trying to say something accurately, it's a worthless effort and here is why.

What process are you performing to document your frames? As far as I see you've listed results and analysis but no method by which you came to them. Everyone knows that frames vary wildly depending on more than just graphics settings.

-Being on the ground, being in certain locations, where are you?

-Looking in certain directions, I can look up and get another 40 frames?

-what is going on in the mission at the time, including combat?

-what mission, and what is is doing?

Then we have how you measured them:

Occulus app or in game counter?

Take over time or point in time?

Averages? If not averages, how calculated? Mean, median or mode?

Then we have your testing conditions

Installation of mods?

Non default settings and configuration

Nvidia/AMD global or app settings?

Running other software that consumes CPU

Point in case, I can load the same mission and record completely different frames by doing different things. Without even the mission, who knows how you arrived at your conclusion? Even with the mission and testing criteria, I can simulate frame drops by spawning or putting planes in combat or missiles in flight.

I don't deny DCS performance is at best hard to get in VR, but the numbers and graphs have little to no value without how you got them.

And that works does it?

Don't really know. Just saw it. I get 45 without ASW on. 35 when the mirrors are on. I also do not have cockpit shadows on. I'll try to take a picture of the options later.

A constructive post ? !!!

... it's a worthless effort and here is why.

Hi there !

Many thanks for your nice post !

The repeatability of the results in the last 4 tests, should tell you a lot about the quality of the measurement method; if you had elementary knowledge about statistics, measurements and uncertainties.

I will not go into this.

If you wanted to know how I do the test all you had to do is ask. I would be glad to describe it.

Also, from the very first post (RTFP !!! LOL ) :

... test flight which is the Nevada free flight with the KA50.

But judging something you do not know and calling it worthless, it's, well.. tactless.

Have fun !
