DCS 2.7 beta > 4k, low, v-sync off, full screen > Instant Action > Caucases > Su-25T > Target Practice 50fps

[TDBONE1]

Windows 11 + 5600x + 3080 ti 12GB + 16GB ram + 5400rpm hard drive 2.5"

just like the title says.

50fps right when you enter the map right after you hit "Fly" button.

i use cursor keys on keyboard to goto right above the roof tops and also 50fps.

no action going on what so ever.

 

what is going on?

how am i going to VR game at 4k with this specific game when it cant even do 50fps on my tv in 4k?

no dlss... no fsr...

 

are ppl with vr just setting a lower headset resolution because from my research if it cant play at 50fps with my hardware at 4k-Low than how can it play 4k in vr?

 

any info would be great and since there is no in game benchmark tool i just picked something everyone with the game can test.

its all free included maps and planes.

 

i hope i have some setting wrong or something.

forgot to add the game mode and OS

There are those that play and those that count fps.

If you think you should have better performance please upload your dcs.log.

Win11 may work with DCS but is not supported.

Slow hard drive may produce stutters and freezes when loading during gameplay.

   Also, please note that 50 fps at 4K is equivalent of 200 fps at 1080p from a GPU point of view.

This, or reduce settings, or both.

Without knowing you graphics options its a bit hard to help you...

Nope - sorry. Doesn't scale this way. The penelty for higher resolution isn't as bad. (Simply put. More pixels to push, but not more triangles to draw.)

On topic, with his setup, OP should be able to hit triple digit fps (with medium to high settings - at least on the caucasus map). If it is just himself. Only problem could be loads of AI-Stuff happening and choking the poor little 5600. I assume there is something off.....

You could test the performance of your setup with this benchmark scene: (you can see how much any setting impacts the performance - thera are some nasty combinations you should avoid. Would be best if you posted your settings page here)

...and those who do both at different occasions and have fun with either of them. It's two hobbies. One is flying Aircraft, the other one is tinkering with stuff, optimizing tech and figuring out how stuff works. I learned a ton about computers by trying to find the final fps. (or the last bytes of expanded memory back in the Falcon 3.0 days.)

all that info is great and much appreciated. will be looking at that benchmark test by Hiob soon.

i thought i didnt need a screenshot of my settings because i said i was at 4k and then i select the quality option of "Low"

isnt that enough data needed or should i take an actual screenshot still?

No, if you choose the default "low" option from the menu, it's ok. Check if you have "wake turbulence" deactivated in the gameplay settings. That can cost a lot of performance in certain scenarios as well.

As I mentioned 50 fps with low settings is way too low. (In 2D! VR - different story).

Have you activated some kind of V-sync? (Check the Ncidia control panel as well). It's in the title - stupid me...

What kind of refresh rate can your TV support? And check the display settings in windows itself.

(If your TV doesn't support HDMI 2.1 and isn't especially dedicated to gaming, it may very well have a refresh rate of only 50/60Hz. Even if it doubles or multiplies that internally, which some TV do, it only accepts input signals of 50/60Hz.)

will check gameplay settings for wake turbulence. its default as i havent touched it.

my lg 43" can do 1080@120hz or 2160p@60hz but i disable v-sync so that should tell me the fps that my computer hardware actually does (i think).

 

[Hiob]

Yeah, I think we can rule that one out.

Ok I checked the mission. I get around 120 fps in 4K with (mostly) high settings (3080 non-ti, 5900x).

There is a problem somewhere. Try to do a DCS repair and delete the metashader and fxo folder in the savedgames folder. Reset the NVCP to default (It's mostly pointless to change anything there anyway).

Have you Afterburner/RTSS running? Can you check clockspeeds, temps memory usage on CPU and GPU?

Ok, I did a small Benchmark scene with your IA-Mission in the Caucasus. See attached file (sorry for the wobly flight, I had no controls set up).

Those are the results:

22-06-2022, 20:19:54 DCS.exe benchmark completed, 5315 frames rendered in 49.187 s
                     Average framerate  :  108.0 FPS
                     Minimum framerate  :  100.9 FPS
                     Maximum framerate  :  115.1 FPS
                     1% low framerate   :  100.5 FPS
                     0.1% low framerate :   94.7 FPS

Those are my settings: (plus I had Reshade enabled)

Start and Stop the record when the head moves to get comparable results.

Edit:

Oh - I found your Problem.

What do you pay for the solution?

(Kidding)

You're most likely getting way too much fps. DCS is by default capped at 180. When you get more than (or close to) this - weird things starts to happen.

You can either limit the max fps in the NVCP to 120 e.g. OR modify a line in the /DCS/Config/graphics.lua from "maxfps = 180" to "maxfps = 300". (line 428)

(Or simply ramp up the visual fidelity).

Let me know if that solves your problem!

 

Edit2:

Results with Settings to "low":

22-06-2022, 20:38:50 DCS.exe benchmark completed, 8123 frames rendered in 49.094 s
                     Average framerate  :  165.4 FPS
                     Minimum framerate  :  158.6 FPS
                     Maximum framerate  :  173.5 FPS
                     1% low framerate   :  152.0 FPS
                     0.1% low framerate :  124.1 FPS

Yes, you are right, I was over-simplifying ... still on many games the performance difference is close to 100% on 1080p vs 4K

was going to try and edit the .lua file but windows 11 notepad didnt work so i went to the ms store and got some lua app under utilities and tools but it didnt work so i just capped it in the nvidia settings app.

worked great and thanks.

i get 120 in 4k medium and i think it was 65 or 50 in 4k high. i will make new test of it but all i do is hit fly for IA, Su25t and "target practice" since the other benchmark dont work correctly.

cant wait til you make the one you said. i think its still needed by the community.

its one of the first ways to tell if your system is working correctly.

think the benchmark map would be valued.

thanks again everyone.

cant wait to get a hotas and vr.

i was really worried with it only showing 50fps

 

[Hiob]

Glad it helped.
Search the web for Notepad++. It‘s on of the best and most common text editors. Just right click the file and select „open with“.

The default editor of windows should work as well,  but Notepad++ is far better anyway.

The downside to editing the graphic.lua directly is, that it is overwritten with any update of DCS . So the other ways are the better solutions anyway.

IMHO(!) Why having such a beast of GPU and then settle with low or medium settings? (Unless in VR) doesn’t make sense to me.

 

Oh, and the MS Store can go <profanity> itself. The good stuff is free on the internet and doesn’t require a lock in.
