Make sense? Release runs 3x FPS better than OpenBeta?

[Fakum]

I have been tinkering with OpenBeta 2.5.1 graphics for a while now, trying to figure out why OpenBeta peaks at 30 FPS for me when comparing it to Release 2.5.0 using the same Instant action scenario for testing? For me anyway. I have all of the similar graphics options set identical. I have no MODS for either, and the 'MAXFPS' in either is not restricting the OpenBeta, nor do i have a custom 'Auto.exe.bat' setup to limit 'MAXFPS' in the Beta? I spent alot of time in the Beta options just changing various settings, the only result from that experiment was occasional FPS loss. What should i be tinkering with in the BETA to increase the FPS to be close to what Release is running at, which is about 88 FPS. Thanks for any feedback. Maybe this is typical for the Release to run better, but that is NOT my understanding from what I have researched to date.

Make sure you dont have both MSAA and SSAA on.

[Fakum]

Thank you, but they are both off. Attached is a screen shot of my OpenBeta graphics settings. keep in mind that if the release version shares the same option, it is also set to what you see here. If it is in fact unusual to see such a performance difference between the 2 versions, I suspect that there is something outside of these settings that may be the culprit? That is a guess on my part though.Thanks

If I was troubleshooting symptom like this, I would "reset" both installs by deleting options.lua files in each of them and setting up gfx again, starting with hitting the same "preset" button at the beginning, because that changes some hidden parameters, which are not controlled by remaining options visible on the screen (at least that's how it was in 1.5.x era). Deleting shader cache folders is obvious, so I don't even mention that.

 

 

In the end, there will be some performance differences anyway, as OB has been running smoother on my PC since 2.5.1 (fps are comparable to stable version, but microstutters are greatly reduced), but they should be small - definitely not as much as you see on your PC.

[Fakum]

Thank you sir. sounds like a good approach indeed! By the way, nothing is obvious to me, if you had not mentioned the shader cache folder, I would not have though to do so, so thank you. I will report back soon on results, many thanks

Hi, the Preload radius seems to be kind of too high. May u turn this to 90000-100000.

 

Then maybe u try out to set Cockpit res to 512 but without EVERY FRAME.

 

And check your VR settings. With default VR is active maybe this also can give some trouble ?

[Fakum]

Deleted 'Options.lua' and contents of 'FXO' folder. Loaded DCS and selected PRESET to 'HIGH' and then adjusted all settings to match what is set for the Release version. NO CHANGE in FPS. It almost seems af if the frames are maxed out to 30? But the MAX FPS in the 'Graphics.lua' is set to 120, and there is no 'auto.exe' running is saved games directory?

[Hoffster]

Do you have Nvidia control panel settings set to vsync half refresh rate?

[Fakum]

I will look into where that setting would be, but keep in mind that the release version is running at 88 FPS, so wouldnt you think that if it was an NVIDIA setting, it would limit the Release version as well?

[Fakum]

By the way, it is set to 'Use 3D application'.

see what happens if you turn on nvidia Shadowplay (overlay).. may have some relative effect.. also, if you havent, check this thread.. https://forums.eagle.ru/showthread.php?t=203644

[Fakum]

Seems that NVIDIA ' In Game Overlay' is the culprit for the Open Beta version, yet it has no impact on the Release version? With In Game Overlay OFF, FPS in OpenBeta is LOW, when In Game Overlay in ON, FPS is High? I would expect it to be opposite? But either way, the In Game Overlay On or Off running the Release Version, has NO impact?

interesting... did you try the autoexec.cfg modification to set max fps to 120 yet.. seems it helped a few people..

 

 

by Washout "Go to C:\Users\yourname\Saved Games\DCS.openbeta\Config

 

Create a text file called autoexec.cfg and add the line

 

options.graphics.maxfps = 120;

 

Set the max FPS to what you want, save and run.

 

If you already have the autoexec.cfg from custom skins just add the line to the file"

GF Experience - whoa, I've never thought about that possibility. Probably because I don't use the GFE, avoiding this bloated hogwash software If I can (recommend doing the same unless your really, REALLy need it for Shadowplay - the only remotely good thing included in it). The fps impact is puzzling and counter-intuitive, though.

completely agree... would recommend DDU complete uninstall of current driver, install of best driver(im still on 390.33), and DDU cleanup and removal of "Geforce Experiences".. then disable nvidia telemetry container in services.. leaving you with only what you need... your GPU, your GPU driver, and Nvidia Control Panel..

[Fakum]

I am in the process again of wiping that drive and restoring it. I will then see if GF Expierience is loaded on that backup? I dont want it at all, but it is certainly a player in this matter. I still have no idea though what its not effecting the Release version. I dont really care at the moment as I want to get Open Beta up to optimal FPS.

[Fakum]

One of my experiments earlier today was an uninstall of all NVIDIA, and installed just an updated driver. It did not yield any good results? I dont know anything about "nvidia telemetry container in services" but Im sure I can figure it out. Oh, I did NVIDIA uninstall only through UNINSTALL PROGRAMS, not through Device manager, then I deleted NVIDIA folders in both C drive Program Folders, maybe that approach to Uninstall NVIDIA is not the best method?

quick question, what is "optimal fps"... because for me, on a 60hz 4k screen, optimal is 60fps... no more or less than needed... gpu only doing what is necessary..

[Fakum]

Optimal to me is, the simple fact that DCS Release is running at say 70 FPS, and while in the identical Instant Action scenerio, OpenBeta is running at substantially lees with the same graphics settings. Now we have already established that the reason OpenBeta is running so low when compared to release is because NVIDIA In-Game Overlay was OFF. When I turned it on, OpenBeta Was running pretty much the same as the Release version. This is Optimal to me, and that is where i would like to keep it. Make sense so far?

 

 

Now, I just did another restore and found that NVIDIA GF Experience is NOT installed,

 

 

 

 

 

 

and OPENBeta is running at low FPS. So since GF Experience is NOT installed, and we determined that turning ON In-Game Overlay improves the FPS substantially, how do i proceed?

well.. you would not be able to use Nvidia Overlay without Geforce Experience obviously... so your only other option if you choose to not use Geforce experience would be to try the "autoexc.cfg" modification which has also yielded similar performance restoration in some circumstances..

...or... Install Geforce Experience.

I have tried the autoexec.cfg, but there was no difference. next option is a bit confusing though? I should install an overlay feature from a 3rd party (NVIDIA) to get the FPS increase for DCS OpenBeta, and the Release version runs fine without it? Maybe I shouldn't be focused on the performance issues between OpenBeta and Release, but its my understanding that they should be performing relatively close to each other, and they do, If i use Overlay from NVIDIA. I hope I am explaining myself well? LOL

you are explaining perfectly... and they probably should be performing relatively close to eachother... but Open Beta will always likely have more bugs than Release as it is more of the testing platform on which to build the next Release version or test module compatability.. so you may have just tweak around and see what works well with your configuration.. on my setup, they both run almost identically though..

[Fakum]

I appreciate your feedback, and im happy to know that I am being clear. This is not my field of expertise. I do understand that there are likely to be some differences between the 2 versions. What baffles me currently is that OpenBeta runs just fine if I install NVIDIA Overlay? That just does not make sense to me at the moment. and If I elected NOT to install it, I would be left to spend yet alot more time trying to figure out how to get it back to some sort of performance level that is somewhat close to the release version, and knowing that Overlay can do this by just enabling it tells me that the potential to run OpenBeta at or near Release version performance is a matter of some configuration combination, not to mention that the current settings between Release and OpenBeta are matched for the purposes of comparing differences. Interesting matter for me any way.

[DflippinK]

no problem friend.. glad you at least got it back to speed with the Overlay for now..
