[REPORTED] Performance Issues

[Proteuswave]

yeah i think it's not about hardware, it's about code.

i just disconnected my vr gear to see what kind of performance i get with my "good" system specs in 2d.

 

55fps with the supercarrier cold start mission (vsync off)

2080ti, 3900x, 32gb

 

LOW preset settings, except shadow on low

1080p!

 

So i would expect a little more from those specs tbh.

 

Exactly with those specs I expect you to be running high settings with way more FPS.

Moved the camera away from the Supercarrier (just for the lower LODs to kick in) and then zoomed in to see what's happening.

 

No shadows & simplified crew - 45 fps:

 

 

Moved the camera slightly closer, and along with the shadows & detailed crew came the huge drop to 28 fps:

As you can see, the difference in polygons is insignificant (7,6 mil vs 8 mil).

It's very unlikely that 400.000 polygons can cause a 38% performance hit.

So maybe it is indeed the shadows from the animated crew?

 

From my previous tests I can conclude this:

 

shadows without crew = great performance

crew without shadows = great performance

partial crew with shadows = tolerable performance

full crew with shadows = terrible performance

Hi,

I was interested in the difference framerate when set High against Low presets.

I used the basic mission of the cold start as a benchmark, which takes 1:45s long.

Data are from the internal Bench test MSI Afterburner.

Can you please try, there are significant frame drops in time 1 min, thank you.

 

Extra setting:

Resolution = 2560 x 1440

SSLR = Off

Mirror = Off

 

Setting preset High.

Minimum framerate : 13.4 FPS

Maximum framerate : 84.4 FPS

1% low framerate : 14.1 FPS

Setting preset Low.

I wonder if this is the cause of our frame rate issues on the SC? Double shadows been posted about on another part of the forum.

i noticed that you get way more perf with .,.. duh ... simpler models if you replace the f-18 block 20's with F_A-18c's you get a corresponding frame rate boost

 

the double and triple shadows thing is fascinating as well though

interesting. how do you switch between "Lot 20" and regular F/A 18c model. Mine always comes up and shows "Lot 20"

[speed-of-heat]

You have to select F_a-18c , .. it only works for ai or statics

2.5.6.50979 (released today) - still not fixed.

 

It's been almost a month, but we still haven't heard a single word from the devs.

 

Considering that the next patch is a whole month away, I really hope that their "investigation" will finally bear fruit.

I have a small performance increase after today's patch :)

Ditto, at least in daylight play. Haven't tested night yet.

[petsild]

In the last beta is a better framerate, it only applies to the default shadow and the view of the island. Still in the course of service on the board occurs framerate drops mission cold start.

More than 30 days after launch:

 

Hornet Cold Start Mission on Stennis: 108fps

Hornet Cold Start Mission on SuperLag: 38fps

 

Seriously ED?

[Minsky]

*sigh*

 

2.5.6.52196 (released today) - no performance improvements.

 

It's been two months and seven patches without a single meaningful word from the devs.

Well they had one word on it (investigating) but that's getting ridiculous.

wow, hopefully there is breaking news soon. But i should be careful how I use that term "breaking". Let's try, "Hopefully there is performance news soon"!!!

[ebabil]

I regret buying this module because of this performance problems. Now I don't want to use high fps stennis because SC is sitting there. Yesterday I saw 16-30 fps. As soon as I took off, fps reached 50-60

Ouch. Man, what do we do with this 16-30 is kind, i get lower than that at times.

[ebabil]

16 fps is a slide show, how come you get lower than that? those low fps issues hurt my feelings as if my pc is in severe pain :D

[[SFS]JDAM]

I get 70 fps in multiplayer. But my graphics card is a GTX 2070 and 32 GB of RAM

Please take a screenshot of your ingame settings and attach here, we maybe able to give you some tips

Hi all,

 

just to share my experience.

 

I have better frame rate than ever in the SC in VR. I use a lot of mods, a full crowded deck, scripts, etc, so, i can´t blame (and i don´t because it´s not the point why we are here sharing experiences and helping each other) ED for any frame loss i may have, because with vanilla version it´s smooth. I got 30 FPS in VR, less stutter and a better experience. When far from the carrier i get 45 FPS when before that was not the case. There is optimization to be done, the frame loss when looking at the island is less noticeable (vanilla version) but it´s there. Overall i think it´s headed in a good way for now. All of this is subjective because every rig its different, different settings, and so on.

 

My overall specs:

 

-4790k 5.5GHZ

-32GB Ram DDR 3 1800mhz

-SSD´s x3

-Zotac GTX1080ti AMP Extreme Core Edition 11gb DDR5x

&

- Valve Index

 

Config:

 

-Valve Index SteamVR: 120hz refresh rate

-Valve Index SteamVR Supersampling: 1.0

 

DCS general options:

 

-VR pixel density: 1.5

-MSAA 2x

-SSAA 0

-Shadows to Flat only

-16x anisotropic filtering

-Visibility High

-Textures HIGH

-VSync off/Fast (in Nvidia options)

 

EDIT: forgot to mention, usually my frame drops happens as soon i start the batterie in the Hornet, nothing much but that´s why i said there´s room for improvement.

 

Now i´m quite happy with Viper, Hornet and Supercarrier performance in VR.

 

Best regards,

F.

I´m sorry, that is wrong. I mean 4.5ghz, don´t know where i got the 5.5ghz... maybe too much workload. Again, my apologies.
