2.9 update and reduced framerate

[FLAKK88]

Anyone experiencing poor framerate since 2.9????  I'm running triples 11520x6480 on 4090 native "No NVIDIA Surround", high end settings are in place in game...  Prior to DCS 2.9, I would get 50fps on ground...  Flying the F16 on Caucasus at about 15 thousand feet..  The framerate would be between 70 - 90fps.  Now after the update..  I'm sitting at 25-30 fps..  All drivers are up to date..  The game performs like Crap!!!!  

 

Was wondering if others experienced the same hit???

 

Thx..

11520x6480?! What kind of screens are those? I’m surprised you’re even getting 30FPS 

[The_Nephilim]

your resolution on the one is not times by 3. so it is just 2160.. I know you said it was ok but now it is real bad but running it in 3Viewports is inefficient.. it is best to run in nvidia surround and set the display as 1 display vs 3..

Did you run a clean and slow repair after the update??

How it can be related to performance issues even theoretically?

well then maybe you can tell me what is wrong I am only trying to help you resolve your issue. if you dont think it is that well you would be told to do it even if you sent a ticket..

but just ti kill the curiosity, during the update you could have got corrupted file and cause an issue like this. either clean and repair or do a totasl reinstall. either way it will eliminat that as being the issue.

 

But maybe a log file could explain it too or even a trk file would be good.. IDK!!

 

Oh and as to your OP Question I do not experience any of your issues with the new update past present or probally future..

Hi, 

Same thing for me since the new update. Same settings (with a 4090 too), same PC, in VR. 

I notice a drop in fluidity, stutters (which I hadn't seen for a while). With the F-4 for example.

Best regards.

[Falcko]

For me also since this update, before this update it was really smooth. Now not so much, lots of stutters.

[Kovacs]

For me a lot of stutters, the game freezes at times . Unplayable and unpleasant in combat. And as much with high settings as with the basic ones.
Before this version the game was a delight.

[Kenan]

I find it amazing, reading the threads where players refer to post-update drop of performance (meaning, before the update, DCS ran fine) that there are people on this forum twisting themselves in knots, trying to treat this is as a "user-related" error and offering many "solutions". The only true solution is a new performance-fixing patch. Too many people are experiencing these issues for it to be treated as a coincidence.

I am having these stutters as well. Why would I now have to "fix" something that was working pre-patch, and with a fairly good PC specs? Why did I invest money to buy better hardware if I'm going to have to "figure out" how to get back the previous performance because the patch messed  it up in the first place?

So yeah, I am going to wait and hope for the next patch..hoping QC is not gonna mess it up this time..

Not everyone wants to wait for a patch to keep playing. Not rocket science....

 

Your basically saying nobody should try and play the game because the player has to lift a finger to get the game working again.

 

Some are thankful that people try to help others, guess you're not.

well said.

 

And for me I got a boost in FPS with the last update, go figure.

Well if the patch messed it up how come not everybody is affected,. I for one am not having any stutters after installing the latest?? there is a common theme here and some get issueswhile others don't..

 

If it was something in the patch everybody who upgraded would be affected.. but who knows..

"Lift a finger"? That would imply an easy fix. And that is not the case here, if you are reading the same threads as I do, that is.

So, majority of people here who are experiencing problems with the patch are yet to find a "lift a finger" type of solution you're referring to. For most of us it's far more workload than that. So, I hope you understand my frustration here. And where exactly in my post I implied that "nobody should try and play the game" because of these issues? Please do tell. I think it was quite clear I was speaking on my own behalf?

[FLAKK88]

The_Nephilim -> You are correct my bad it is 11520x2160...  Regarding Nvidia surround is not viable its worst..  I tried this..  You get better performance with Native triples within DCS ..  Unless 2.9 messed this up..  The video card requires my GPU work harder to use NVidia Surround in DCS..  Big performance hit...  Also did a clean install, and repair same crap..  I wish these developers stop mucking with the game making triple screen support worst..

 

SharpeXB -> I am using "Three" LG G3 65 inch TVs as PC displays.  Attached to the video card are three Display port to HDMI adapter which support Gsync, VRR, 4K, HDR, 120hz...  

 

 

Kenan -> You hit the nail on the head...  I spent well of 10k on my flight rig system..  This game pre 2.9 was running very well.  I enjoyed the Immersive playability, made me feel that the money was well spent...  Now these coders destroyed the game with bloat ware menus and claim performance enhancements which is well below standards..  I don't even enjoy playing it any more, because of the horrible dynamics...  Now they expect players to just sit and wait until a "Promise" patch can address these issues..  Not holding my breath..  The issue is DCS has no competition in the flight space, so "yeah" they will continue to drop the ball, making no one the wiser.  

 

 

Anyways - In the meantime I was hoping that a forum member had a side door fix, but it seems evident that this is definitely a systemic problem.  DCS if you happen to read this..  Get your act together..

It seems to me that would be a resolution of 3840x2160 x 3. So 11540x2160. How do you get 11540x6480? (Oh I see your note above) In any case that’s a lot of pixels, enough to challenge even a 4090. I wouldn’t say “The game performs like crap” because you get low fps running 3x 4K displays. I get 100-120 FPS on a single 4K screen using a 4090. Divide that by three and 30 FPS sounds about right.
But if you think there’s a bug or something you need to include your Dxdiag, a track and log file.

Hi, 

For me the issue was linked to the last NVIDIA drivers !!! (in VR) I've just installed 560.70 again and it works perfectly. 

Regards

[FLAKK88]

SharpeXB ->  I am going to say this again.  With my setup I was able to achieve between 70 to 90 fps in flight using the resolution stated pre 2.9.  Please don't insult my intelligence. I put plenty of money into my sim.  I am simply making a point that post 2.8 destroyed my performance and others shared the same experience.  

 

Cheers

Kovacs ->  Already rolled back drivers for nvidia to about 8 previous versions.  Did not help one bit.

Tip: clean your old shader cache files with Windows Disk Cleanup.

[LucShep]

@FLAKK88 and anyone interested:
I know my post will sound as a generic response but, IMO, it's worth a try if nothing else is working...

In my own experience, with mine and many other systems with Nvidia GPUs (older or newer), the Nvidia's driver 537.58 is still consistently the best, and by quite a margin.
It can make a difference (for the better) with frametimes, increasing performance and reducing stuttering.
I know it sounds strange how an older driver can be better but...  that's just how it is.

Regardless, and no matter what Nvidia GPU model or driver version, I strongly recommend installing only "Clean Version" drivers, instead of official Nvidia ones.
These clean drivers differ in the removal all of the bloatware that you get with the official ones (which causes higher resources consuming with added unnecessary processes in background, affecting and interfering with performance). 

For the mentioned Nvidia 537.58 drivers, its "Clean Version" is found among other older ones in the following link: 
https://mega.nz/folder/dQRX3AQI#9RmtXT0cTw45RsWxTQgYiw

If you insist in always using the very latest Nvidia driver version, then its newest "Clean Version" is (currently) found here:
https://forums.guru3d.com/threads/rtx-560-70-exostenza-edition™.452356/


There's also the matter of Nvidia driver settings
If you have the patience to try someone else's settings, I suggest trying same as mine:

(click on image to enlarge it)


Please pay attention to the following - my global settings may be different to yours.
So, when you see "Use Global Setting" in my settings there, pay special attention to what appears inside parenthesis right after it (it's what it's set at in my Nvidia CP settings).
Change accordingly.
Also note, I've set Vertical Sync at "Fast" because it works best for me (but try it?). It should work good, but if it doesn't try ON or OFF instead.
Once you finish with the changes, click "Apply" on the bottom.

One important setting to change imediately in the NVIDIA Global Settings is the Shader Cache Size, to be set at 10GB (this is pretty much a "must do").

NOTE: If at some point you wish to revert again to default DCS profile settings, and start all over again (for whatever reason), then click "Restore".
And you'll have a DCS profile clean sheet all over again. Play around with stuff.

That’s really surprising. Are you running the same settings as before?

If you want to make an actual report you’ll need to post a track of the mission, Dxdiag, system specs your settings and log file. Also remove any unofficial Mods if you’re using those.

Yes,since the latest update,my frame rates have dropped considerably. I've tried numerous suggestions including a reinstall of the game. A fix or at least a simplified how to is in order.

@LucShep, I was wondering, does it matter how much VRAM you card has? Mine has only 8GB VRAM.

There is no problem and, actually, no influence on GPU memory.
It only lightly affects storage space in the drive where you have the OS (your NVME, SSD, HDD, whichever type of storage you use for it).  

The thing with this setting is that every single game tends to compile shaders in specific folders for the Nvidia shader cache.* 
The default set is size is 1GB, I think? (IIRC, and hasn't changed for many years).

What happens is that, once these specific folders for the Nvidia shader cache get "full", it interferes with that compiling exercise.
And given that most games today are far more complex than they were a decade (or more) ago, it does tend to get filled to 1GB much faster than before. 
...and so, there we go with the dance of recompiling shaders during gaming, which causes long loadings and some stuttering/hanging while doing the job....
While this may be normal on the first time you run a game, it should not be so in its subsequent usage - but it does because the lack of space forces the recompiling again.

Increasing it to 10GB will suffice to solve this issue (some even increase it to 100GB but that's way overkill).

* PS: do not confuse this with the DCS shaders compiling (FXO, Metashaders) in user Saves folder, it is not related.

As a separate (side) note, sometimes deleting this Nvidia shader cache may help with rendering issues, artifacts, and stuttering, etc (due to broken shaders).

so IF I install these older drivers and currently have no issues will I still see an improvemnt in Frametimes and such or will it just baiscally run the same for me? I guess I would need to test it for myself just wondering ..

 

 

EDIT: I gave it a shot performancve was a little bit worse.. but not too bad only about 1ms in the apache with the tedac running..
