I am optimistic.

Sure, give it a go once the patch is live, but as far as I am aware we have not got to the bottom of the issues some users are seeing, so don't expect a magic resolution

Returned now from deep sea patrol. Screenshot taken 85 km from nearest land (i got 35900 preload radius), only sea, me and moon, and Petrovich ofcourse. Just look how my GPU hardly used, CPU sleeps (because nothing is nearby), EDIT: FPS is locked at 60 by Vsync this is important, because if it were 180 FPS, the graphics card would actually be loaded.

@Miro I have to dissuade you of something. CPU and GPU load are never good indicators of performance or lack thereof. Sure, sometimes they are useful in determining a problem in certain cases, but for the most part they can not be used to determine whether software is well or badly optimized.

I fully agree with you, I am trying to show that maybe there is a problem here, I do not have screenshots from previous patches, but often as I checked it, even over land, the load was around 68%, Only over large cities it was 100% and slight drops in frames. I just put in everything that can lead the creators to some trail.

720P?

 @BIGNEWY I have installed the Stable Version and between the OB and Stable there is, on average a 16 fps difference in any given mission when the system is running ok. Thats 20% on my rig.  Configs are Identical and Im running the very latest GPU drivers (Ive have also tried my old favoured 425 NV drivers with the same results).  There clearly is a problem, even if it is just for some.  I am happy to provide trks for both but is there any other information you also need?

[Sr.]

Don't have a trk file or recording to offer up but I do have fpsVR logs.

I had been away from DCS or my computer altogether for a couple months.

First pic is where my performance was when I left, 2nd is last couple days.

 

These are mostly flying FA/18 free flight, Caucuses.

patch is live, test and let us know if you see any difference. 

thanks

No one is saying there is not a problem, but not everyone are seeing problems, and we have not found a reason for the issues currently some people are seeing. 

We continue to investigating, if you have short track replays showing an issue please attach them

@BIGNEWY, with all due respect, a track file is not going to show any problems on its own. We can see that ED have made graphical enhancements (which in my opinion at least, are quite stunning) and following that, as perhaps might be expected, there is a measurable increase in both GPU and CPU frametimes, leading to a decrease in FPS.

It is relatively easy to measure. Create a simple track file in 2.7.6. Replay it in 2.7.6 and capture framerate/FPS averages over the whole track (in VR for example, FPSVR does this very accurately). Then replay the track file in 2.7.7 with the same rig and settings and repeat the capture and compare the results. I can't believe the ED developers have not done something similar and must be well aware. Personally, I have seperate 2.7.6 ans 2.7.7 installs and measure an average 8-10 FPS reduction in VR with that method.

Unless users were already running close to the limit of what their rig and settings can handle smoothly, this might go unnoticed (which no doubt explains why not everyone is seeing a problem). But it's apparent from this thread that many users are at that limit now.

maybe not, but it is a base to start from, we will try to reproduce using the same scenario, attach your dcs.log also and options.lua and we get a better picture. 

But also note everyone's machines settings drivers and hardware performance can be different. 

[MattCri]

new patch makes zero difference on my system, still getting around 20- 30% fps loss

cleaned metashader/fxo and shader cache on windows and amd drivers before launching, short track uploaded. Very short and simple track, basically no ai, just flying straight.

dcs.log test patch 2810.trk options.lua

Failure to recognize the problem is to belittle users.  This post (hidden medium) where it speaks for itself, if you go through Discord, Reddit, the people who have this problem are many.  And there is another even greater one that does not participate in the networks that have told me that they also have fps drops.  Without another word.

Well... looks like i could use my money, spent on AH-64 preorder, better....

I’m holding off on this one I saw a lot of stuttering on the videos wags released, and if it’s stuttering on their systems what hope do we have 

[heroe]

no changes for me, I still have low FPS

[MattCri]

in my opinion if you have a  fairly strong gpu and usually cap the game at 60 fps there is no way you are able the see any degradation

 

my gpu is quite weak and i have nearly zero loss of performance in the heaviest situations (marianas, big cities at very low altitude, on ground at huge airports with lots of units) but a massive 50fps loss at high altitude with external cam and only sky and my plane rendered.

New patch Installed. Using the method I described above I can actually see a small improvement of about 2 FPS in VR.

For me 3-4 FPS Gain, still 10 FPS less than pre October 20

In these last two updates the FPS lowered a lot and the only visual change is the water and its reflections, knowing that the water is under the entire map in DCS including under the ground, this is the most likely factor of the low performance, Before that I had the water on HIGH now I put it on MEDIUM but still it shoots a lot less FPS than before.

Same issues. Clean FXO and Meta, clean NV cache 1 of 2 - trk of stable to follow

No noticeable change after patch: however; 

While pre patch, I had always run SteamVR Super sampling at 100%, sometimes 130% and had great visual clarity, 45fps with motion smoothing and no stutter flight... I decided to start lowering it with this patch. There was no change at all until I got to 60% SVRSS(8:46). While I did get back to pre patch 45fps and very smooth flight, I did loose (expectedly) clarity.

Is it possible someone simply fudged up the IPD multiplier or how it relates to SVR super sampling?

if it was IPD wouldn't be that bad for everyone... try resetting the IPD to 1.1 and the running a mission and then resetting it back to 1?

Yeah 1.1 regains some clarity but gets me back to about the same as if I run at 80-100% SVRSS

Seriously, do you think tackling ED in such a way helps in any way?

First - ED has NOT negated that there is an issue. Just pointed out, that it does not effect ALL users (as usual) and therefore is hard to pin down.

Second - Bignewy acknoledged the problem and stated early, that they don't have a solution, YET.

Third - You're on open BETA!!!

Suggestion, quit the whining and try to help with some facts.

 

EVERY SINGLE TIME - the same drama....

and then reset ? back to 1?
