I exceed recommended hardware posted in FAQ - is it my fault that I get low FPS then?

[Gierasimov]

OK, looks stunningly beautiful but...

 

From the FAQ:

 

RECOMMENDED SYSTEM REQUIREMENTS (HIGH graphics preset settings): OS 64-bit Windows 8/10; DirectX11; CPU: Core i5+ at 4+ GHz or AMD FX / Ryzen; RAM: 16 GB (32 GB for heavy missions); Free hard disk space: 120 GB on Solid State Drive (SSD); Discrete video card NVIDIA GeForce GTX 1080 / AMD Radeon RX VEGA 64 or better; Joystick; requires internet activation.

 

 

I am on a Windows 10, I7-10700K (5.1 GHz), 64 GB RAM (3000 MHz), RTX 3080.

 

Also from the FAQ:

 

Despite being an island map, you can expect similar performance to the Syria map

 

So, Syria map gives me constant 60 FPS (consistent with my screen capability) and empty Andersen AB I get 40, Guam @ 3000 feet MSL I get 30-40, at 700 feet I get 30-40.

 

Ocean alone at 1000 feet MSL shows as 80 fps, whereas Mediterranean sea on Syria map gives 120 fps at the same alt. 

 

I guess I need to wait for optimizations?

 

 

 

[rubbra]

I'm towards the bottom end of any specs, especially for VR, but can get a solid 35-45 fps in VR depending on what I'm flying over for Syria, solid 60 (vsynced) in flatscreen mode.

 

Same settings for Marianas... 16-18fps. Flatscreen mode, also 18fps.  That doesn't make much sense to me!

 

More specifically, if it helps anyone:

 

Marianas at 2000ft:  flying over open sea at in the FA/18, I get 24fps, solidly, until I pull a high-g turn, at which point it drops to 9. Flying over one of the small towns beginning with A, 14-18fps.

 

Syria map at 2000ft - flying over open sea inbound to Akrotiri, 42fps, pretty solidly, slight dip below 40 for high g turn, then 36 when flying over Akrotiri.

It's not you: performance is horrible there for me as well. Especially at low level, it's such a slide show I can't even identify parked aircraft when I fly directly over airbases...

(specs in my signature)

[lt_d4n]

My specs are the same and I get in marianas flying close to the ground around 30-40fps.

 

I find it funny that when people complain about low fps, the answer is that they get better hardware. I think my hardware is more than enough, and the problem is the poor graphical optimization of the simulator

[Heimz]

Been trying to figure out why my FPS tanked so hard in the new Map.   I usually range between 45-60 FPS in Caucasus, NV, or PG multiplayer servers.   I played Marianas in MP AO Aerobatics Server ,with a ping of 54, maybe 40 players, and I was constantly at 14-18 FPS, with occasional dips down to 9.    Put my graphics setting at Low, and it was then only as bad as 11 FPS.    FSP was 14-25 in single player Marianas Map too.    

 

Intel I9 8th Gen, 3.6GHz, 32GB, dedicated 500GB Samsung SSD for DCS only, Nvidia 8GB Quaddro GPU

[sirrah]

Same here

 

All maps are doing just fine (Syria a little more strain than the rest but still very acceptable), but with Marianas when flying over Islands and looking at the ground I get extreme ghosting  

[Dragon1-1]

There's definitely some problem with the islands and their optimization. I think it's a known issue, it's fine over the water. Also, the specs are copypasted from Syria, from the looks of it. The map is actually extremely lightweight, you really don't need 120GB free space, more like 8-10. 

[Aurora juutilainen]

Here is my benchmark as an additional data point 

instant action - F16 - Hotstart
flying around anderson AFB
42-75 FPS  mostly around 42-55 though

I9 9900KS stock settings
32GB @4300MHz  CAS latency 15
GTX 1080Ti stock settings - driver 461.72
dcs running on a Samsung 860 ssd


*edit, did some additional flying around in this instant action mission and fps dropped to 35 occasionally, I imagine having any kind of mission on this map would drop frames to an unplayable level easily.

[pepin1234]

What is the size for this map?

[Scratchy]

There's a vid from the Grim reapers which demonstrates this being a problem with the shadows. (I think the new trees and their shadow maps.)

The solution is to use Flat Shadows. There's 2 spots in configuration where this is set.

If this has already been posted elsewhere, sorry.

I found that my FPS is halved flying low, until I changed to Flat Shadows.

[Hotdognz]

Try flying this map with AI units on it for a mission, its becomes really unplayable, my VR 45fps (reprojection on) went down to 20fps, even after following the GR video and turning shadows off, I run quite high settings as I have top of the line gear 10850K 3090, I know I can drop settings but then it just looks like a map from a game back in 2010 and I don't believe we should be having to do this. up to this point I have had 2.7 running OK Syria was fine, this nap to me is a map that wont get used by a lot of players because of its issues and that in it self is a shame.

I cant see any point in building new stuff for DCS if its not going to come out as playable on the middle of the road gear (which most people have) even in open beta, all you doing is annoying the player base who support you.

Still glad it was free and we didn't have to pay for it, i have now made a note to myself that I will only try any maps that come out from this point on in a free trail so I can see if they are playable or not first before purchase.

[q800]

Like for everyone else: Syria heavy loaded with mission stuff -  50 to 60 (locked by riva at 60). Empty, tiny Marianas - 30-33 low and mid altitude.  

 

Ryzen 2700x

 

RTX 2070

 

32 GB 

 

SSD and so on.

 

From the posted stuff i think we're just at "user's computer's fault. It's all perfect" stage. I give it like, let's be generous, two weeks, before ED admit there's a problem.

Same has been done before the with Aerosoft. For 1 month they tried to convince users that serious bug with throttles end engines' N1 on CJR 700 is user's hardware and calibration problem. Which obviously wasn't. Give it a time.

Flat shadows are known to cause graphical artefacts and glitches. So not a valid option for solution, but maybe worth trying for a temporary workaround.

I have similar specs (apart from the 5900x) and get around 60 FPS when flying around in the hind low level.

 

One thing, I always have though, is ground shadows to flat (can't stand the flickering of default). And I turn off the mirrors because they are useless anyway.

All other settings are fairly high, only thing I did compared to syria is setting viewing distance from ultra to high.

(MSAA 2x, SSAA off, SSLR off, clouds ultra)

Ok, so another one in favor of flat shadows. BTW its flat shadows that were glitching for me, I will try though. 

 

Thanks. 

[Hiob]

The only "glitch" I get with ground shadow is that the shadow of my aircraft sometimes is incomplete (mostly on angled surfaces)

other than that I find the "sharp" edges of ground shadows and the absence of a visible "LoD-Change"-Line more "real" than default.

 

I'd wish they'd improve that, but it's still better than the flickering with default shadows for me...

OK for me here are the results (same track reply):

Track takes 6 minutes to play: 

 

Default shadows:  Average 38 FPS with 3.8% of time below 30 FPS

Flat shadows:        Average 40 FPS with 3.8% of time below 30 FPS

 

[Hiob]

Have you done the usual trouble shooting. Deleting the Shader-Folders etc?.

Can you make a screenshot of your graphic settings?

 

Have you made sure, you're running in fullscreen (alt+enter)?

I read an article about updated graphics for another commercial simulator. There they said that the graphics would give great visual improvements at a lower hardware cost. I don't fly that sim, so I cannot confirm it. However we do know that DCS has a great potential if they could optimize the game engine.

 

I fly in VR and community generated shaders has greatly improved my performance and experience. Based on that there is proof that ED could do a lot to improve things...

What shaders are you using? I am curious to try it out in VR as well. I have been using the universal shader mod that improves detail mostly but no increase in FPS at all.

I use Kegetys shaders. I fly mainly in Caucasus for the record. Works great there. Head over to the VR sub forum and you will find them. There are other versions and shaders as well you can try from other users. 

[Heimz]

Tried Marianas again last night with Flat shadows , then off, then followed Spudknockers tutorial for frame rates.   Still getting anywhere from 9-19 FPS in Marianas, but annoyingly even Caucasus has tanked in 2.7, now get about 20-25 FPS when I was routinely getting 45-60 FPS for the past 2 years.  I'm a TrackIR user, no VR.   

 

Can't stand the ridiculous hit to FPS so I just bought an MSI i9 10900K with 64GB RAM, GeForce 3080 GPU, and 2TB M2 SSD.  Crossing my fingers this makes DCS fun again.  If DCS looks like crap with this, I'm giving the computer to my 8 year old and I'm just gonna fly RC planes.   

[Hotdognz]

As I mostly fly VR I thought I would try the map in 2D mode with everything on max except shadows which were set to flat, my settings are in the picture. I did this as its been touted this new EDGE engine needs high end hardware which I consider myself to have.

System rig

3090 no overclock
64 gig DDR4
i9 10850K with small over clock to 4800mhz

Flight was F16 free flight and also a custom flight with an F18 at sunrise.




FPS counters blown up as they were very small

F16 Day

F18 Sunrise

It looked fantastic but I still consider the FPS to be very low for such high end hardware with how the map looks, it reminds me very much of a map from ARMA 3 like Tanoa

That will run it all fine in 2D mode the Marianas map though with still be around 40 with max detail, see my post above.

 

[MeatServo]

I’ll report something completely different. I have the smoothest performance on Mariana’s. Even loaded up Andersen with +60 statics, and +30 AI aircraft all departing at the same time, base defences, etc. Ran a Pearl Harbour type test with +1000 units on a server. Server ran it better than PG or Syria, and not a dip client side. Smoothest performance I have ever seen flying off the supercarrier. Settings at max, except no SSAA. I don’t run VR. Watch it here.

 

Tacview is a performance hog if you have it running. I also found DCS to like Nvidia's Ultra Low Latency Setting set to Ultra. Doubled my frame rate.
