[REPORTED]2.5.6 Performance

[GunSlingerAUS]

I've set up a very basic mission to train in - Nevada map, single F-14 hot on runway. Everything runs beautifully smooth (50-60fps, latter of which is limit of my display) at 4K resolution with everything maxed except mirrors, scenery, and that new reflections thingy. However, as soon as I add a flight of 4 F-15s with 2 waypoints, and an E3 with 10 waypoints, a get an extremely noticeable stutter every 20 seconds or so. Delete the F-15s and E3, and it's back to perfect performance. No other units on the map.

 

Weird much?

It has been identified that AI are a big part of performance drawback. There is something about the AI aircrafts in 2.5.6.

2.5.6.4591 OB Upgrade on a 10 year old system, it works now.

 

Even though I've been a DCS user for only a couple of months, I though I'd share some info here. You can see my 10 year old system spec's in my signature.

 

Started out with 2.5.5 stable. Even with my outdated hardware I had it running pretty good with medium settings. Hardly ever dropped below 20 FPS. I then decided to try updating to Open Beta v 2.5.6.4591. Here is what I observed. BTW: I also added a 3rd monitor, was using 2 monitors.

 

Test scenario : F/A-18C, open Instant Action, select NTTR 'ready on the ramp'.

 

Settings : Same menu settings as 2.5.5; Monitor setup : 3 HD screens using '3 screen' settings in setup menu, then 3 screens using '1 screen' setup (see below).

 

After the update and sitting on the ramp at Nellis, in default location (no movement) FPS was around 18. Then taxied out to the runway and aligned for takeoff, FPS went to about 7 and very choppy with more of the parked aircraft in view. This was also the case when approaching downtown Vegas from the north.

 

For grins, I changed the monitor setup to '1 Screen'. Repeated the NTTR scenario as above, this time I got 41-44 FPS then at takeoff point it only dropped to 30 FPS! So, I'm now using the '1 Screen' option instead of the '3 Screen' setting, at least on my old hardware. Now I also get 20 FPS flying low-level over downtown Vegas. 8,000 FT AGL flights to the north around Groom Lake with a F/A-18C wing-man I get around 40 FPS. BTW, Nvidia setting is setup with 3 separate monitors only.

 

So... after the upgrade and changing the monitor settings, I'm pretty much back to 2.5.5. performance. I have not run any missions except for my own which all are north of Vegas with 1 F/A-18C wing man and 2 flights of 4 each F-16's and A-10's, Not sure why it works for me with my old hardware. Upgrading to all new PC/hardware is in the works. One an old system like I have, I can live with ~20 FPS at the worst and 40+ flying.

 

I'm still learning the Hornet and DCS. Of note, I have 25+ years designing and building military flight simulators, the last ones were 8ea F/A-18C's for the US Navy and have only 'flew' one simulator after delivery. Also have every flight sim program since the 80's. All I can say is WOW, what a great sim for the F/A-18C! The detail and functionality along with the cockpit and all other graphics is well... outstanding. Being in the development side for years, it's a slow progress sometime to tweak things, simulation code is never really 'finished', always improvements can be made. But, we had government delivery dead lines, so we worked 7 days a week towards the end. So, I will wait patiently for the dev's here to keep on keeping on.

 

A little tidbit on coding simulators, back in the 80's our military contracts stated the system including flight, weapons, radar, GUI, OTW, etc. had to meet a 'realtime' minimum of 30 Hz. These day's it a lot more!

 

 

Here is a screen capture of my current settings:

Hey man, don't take this the wrong way but i feel like we should all get a crowd fund going, given your credentials, to put the cash together for you to upgrade.

Purely so that you can enjoy the sim for ALL it has to offer (i.e. stunning visuals).

I feel genuinely *upset* for you that you have been simming for so long but dont have a top notch rig to see DCS in all it's glory.

 

Again, this isn't a dig in anyway, i genuinely think this should happen! :thumbup::D

I hope i haven't come across rude

[OG84]

I have made another discovery.

 

Created a new mission with just the F16 in parking position with engines running.

I get about 90 FPS.

 

Then I override gear handle and raise it while on the ground.

Frames drop to 9 FPS

 

GPU workload drops significantly but CPU workload stays the same on each core (around 20%)

So maybe also some physics, damage model bottleneck.

 

Thats with a valve index, 2080ti, 7700k 5ghz

[Nightstalker]

I have been playing around all day with different modes. I have the same fps as 2.5.5 as long as there are no AI of note.

 

If I log into a mission such as an Escort the bombers WWII mission my frames will start off at over 100 and slowly drop and drop the closer I get to the AI. When the bombers start dropping their bombs I will drop all the way down to 18 or 19 frames.

 

I booted up an "instant action" scenario where I was sitting in a cold start on the tarmac. My frames were at about 120. A Heli was sitting on the tarmac near me and when I was sitting there looking at it start up my frames dropped by 30-40 frames. This also happened while sitting in a cold start in the F16. I watched 2 vipers taxi past me and my frames just dropped.

 

The problems don't seem to have anything to do with the new shaders or water. I can hop in a warbird and fly across the treetops of Caucasus at a constant 98-100 fps in 2k, high settings, 4xMSAA without a sweat.

[ebabil]

I made some tests on mp server and also single player with tomcat and viper today. my fps problem seem to have gone. I played 2-3 hours with good fps.

I made some tests on mp server and also single player with tomcat and viper today. my fps problem seem to have gone. I played 2-3 hours with good fps.

Same for me.

Just played VR for 1.5h with various F16 instant action and training missions and fps seems to be back at the 2.5.5 level.

[Nightstalker]

I tried mission: DCS_P51_Bomber_Support_Caen_-_Escort

Mission started and I'm 20,000 or so feet up over water with many many planes around. My frame rate was 11 FPS. Using MSI afterburner:

GPU was 49 Degrees , 18%, 0%, 45%

MEM 9663

CPU1 30%

CPU2 9%

CPU3 11%

CPU4 9%

RAM 17360

 

Fly the same plane in the same area on free flight and I would be at 120 or more FPS at 2k resolution, 4xMSAA, settings all on high.

 

I tried mission: DSC_Spitfire_Battle_of_Britain_-_Royal_Fleet

 

Sitting on the ground cold and dark. 120 FPS. Two Spitfires start to taxi past me and my frames drop to around 50 and then slowly go back up.

 

Definitely a link to AI problem.

[MacEwan]

For me it seems like anytime there are ground units involved my FPS drops from a solid 40 to 20-30. Tested on small missions, and playing in VR using a Rift S.

[Fiachra]

After the update it is completely unplayable for me. In single player campaign mission and instant action there is constant stuttering and lag between input and reaction when in F-86. Tried the Mirage and F-5 on the Persian Gulf and Nevada maps and the screen is just blinding white as if staring into sun, as roll plane sometimes a little of panel at bottom of screen is visible, external view is completely white except for the info bar. Using the autoexec.cfg file (https://forums.eagle.ru/showthread.php?t=251377) made no difference.

 

Using a head tracker, never had performance issues before on the highest settings.

Additional information

[med-taha]

I don't know if someone is experiencing the same, but after the last update. I can't see the building until i'm very close.

my load radius is set to max the same thing with the visibility range setting.

Thanks

[markuscha]

DCS is so strange !

With latest Update my frames are back to "normal".

Was cut into half before ...

[Predator-78]

After the last update, the situation seems to have improved but it is certainly not the same as before the problem occurred. Two crashes occurred tonight ... sent the report.

[cdjung1]

Rift S audio issues

 

Since the new update I’ve had two crashes and lost sound through the headphones. I usually run both speakers and the headset, with comms through the headset. Now I get no radio transmissions whether the headset is selected or not.

[Airasys]

Hey Guys,

 

Just to confirm what others a seeing Open Beta performance has dropped by half? I use to get 45+ on high setting in wide FOV Pimax 8K, after the latest update I am lucky if I see 21-23 in the air and on the ground I am seeing as low as 13.

 

I just purchased the JF-17 and I cant even think of trying to taxi even on the lowest settings.

 

Could someone in QA please flag this as a P1 or P0 issue? VR in Open Beta is not possible now :(.

 

Thank you.

[REPORTED]2.5.6 Performance

 

Here are my results with wilbur81 test mission.

 

 

As already reported in the other thread with the ai moving on ob the sim becomes unplayable (8 fps is the highest number) but still the non moving ai version in openbeta is worse then the moving version in release version so apart from the ai moving on not something else is still going on.

 

Tested in 2d with the same settings between open beta and release

[Fang333333]

Hey Guys,

 

I just purchased the JF-17 and I cant even think of trying to taxi even on the lowest settings.

 

This is why I thought it was weird to offer testing and sales during this time. People are gonna hop in the modules and find out they fly terrible right now. Dont get me wrong, I am totally glad that ED is allowing this! Its really cool of ED, no doubt.

 

Its just the worst time to get into DCS right now with the FPS hiatus.

Don't worry, Airasys, everybody is hurting right now.

 

Anyway, congrats on the testing, let us know what we can do to help!

Before 2.5.6 I had constant 45fps in VR for most of the time. But now I struggle to get more then 25 fps...

 

What I noticed by accident was that if I turned off the cockpit illumination in the F16 my frames were back at 45.... even on the ground (most of the time at least)....

As soon as I turn the lights back on my frames drop.

 

There might be some problems with the lightning settings of the cockpit lights. Maybe their quality is set too high or their radius in which they affect objects is too wide.

 

I played the CAP mission on Persian Gulf.

 

Specs:

 

I7 5829K @ 4ghz

16GB DDR4

GTX 1080

Oculus Rift

 

Can someone else confirm this?

I downloaded the F-86f yesterday and grabbed a mission called "Dogfighting_with_Migs". Started the mission in the air at 110 fps and as soon as we engaged the migs the frames dropped right down to 35 and it became unflyable. This has become the common denominator with all of my observed frame rate issues. It's always the AI.

Has anyone checked Nvidia control panel lately? It has changed as well. My performance was altered a bit and I realized there were new settings I had never seen before.

 

 

Also some other changes that made my system fluid like water in vr are VR Shaders Mod 2.5.6, Hotplug Disable (autoexec.cfg), GameDVR Disable.

I ALWAYS double-check my nvidia settings- no change there. Those VR shaders and that hotplug certainly help but still does NOT even get close to the fps I had with beta 2.5.5!

Well, I installed todays OB patch and do not gain a single frame. Placebo patch regarding performance for me. The problem are definitely the ground units especially the moving ones (AI fighters, vehicles etc.). As long as they are static they do not hit fps that much. But as soon as they start to move or to get close to my aircraft, fps start to drop.

Having tested the latest patch with the same mission spawn as my previous post I'm now back to Vsnc'ing at 60 FPS in 2D. I'll test some more but that was 40FPS before the patch.

 

Edit: Seems much better when trying with the 4YA Nevada MP mission offline, but when I turn on the SA page in the F/A-18 the FPS drops to 20. Turn the SA page off and back to 60FPS.

 

Edit 2: SA page works ok on left and right MFD, just the centre one now causes massive FPS drops. Strange thing is the same is now true when running 2.5.5 when I know it was fine before the last patch for 2.5.6. Can the update have modified a config setting or something common to both installs which are running on separate drives?
