solved Framerate lag

[Flapjacks]

So I've had extremely bad framerates for months now and I've been chalking it up to the 2.9 patch, but figured I'd ask to see if possibly it was on my end. My fps is at like 7-10 fps on the ground and low 20's in air. It's the same on both Openbeta, MT Openbeta and Stable (which I have on two difference drives) as well as multiplayer and single player. I don't have any mods anymore I don't think, I've turned off tacview, graphic settings are low, vsync is off as well. Drivers are up to date. I've gone through all kinds of tips and tricks that I've read on a couple of the 2.9 problems posts (power management settings, Nividia control panel settings, etc), I've run slow repairs, deleted fxo and metashader folders. dxdiag and device manager says no problems found with my gpu. I know I need more ram btw (16 gb) but it never ran this bad before. Is there at least any way to check if the problem is on my end or not?

I just had this happen today. I played Thursday and had 0 issues...Turned it on 10 mons ago and it was bad. Unplayable. I'm watching my GPU stats drop. 98% GPU utilization then drop to 1%. Temps are way to low. Was there something that just dropped since Thursday?

Nothing I'm aware of. Another patch is dropping soon though I believe.

hello. i see you are using MSAA. try DLAA. 

you may see ghosting

Hi,

one thing that improved the ghosting for me was to replace the nvngx_dlss.dll file in the Mt-bin directory with the latest version from NVidia.

The version in DCS seems to be 3.5.0, but the latest version I’d 3.5.10.

I got the file from:
https://github.com/NVIDIA/DLSS/tree/2aa0b2c9d07995f517561ab6bbef60308bc7eb3a/lib/Windows_x86_64/rel

 

just back up the original so you can go back if things don’t go so well

easy to try and revert if necessary.

I've tried them all but nothing helps. I have anti-aliasing off for now.

Hi, 

what is your HAGS (Hardware Accelerated GPU Scheduling) settings in windows and do you have game bar active?

Some users have different results with them active and disabled depending on the system.

@Flapjacks in NCP the only things i see different between us

These are in NCP

Antialiasing Mode should be Application Controlled. this lets DCS handle it.

Max Frame Rate OFF. in DCS settings use ON and set at 120.

Texture filtering - Quality is set to QUALITY. try HIGH PERFORMANCE. 

let us know how it goes.

I made those changes but no luck.

Upgrading RAM to 32GB may help, as you are going to be using pagefile more often with 16GB 

Tuning Tips
Set Water to Low.
Enable Full Screen mode.

Still no improvement, I appreciate the help. Think I'm stuck with this.

So a friend of mine recently sent me a video by Spudknocker that proposes a simple fix for stutter in DCS 2.9 related to Windows Defender. I'll link it below. Just for the record I have tried what he suggests and there appears to be improvements in game/stutter.

The TLDR for the video is to make some scan exemptions for Windows Defender related to DCS. I also included an exception for my Steam folder because I have an Index and wanted to include SteamVR in his solution. As always YMMV.

i personally made the exceptions because it was mentioned in other posts. my loading times went from 2 minutes plus to under 30 seconds. i have since suggested adding exceptions to any AV. however before watching this video, i had only the DCS install folder as an exception. i have since added the TrackIR install folder, the APPDATA TrackIR folder, DCS Saved Games folder. thanks to you and Spudknocker.

@Flapjacks it is worth a try.

Gpu is running hot. Gonna see about replacing it and see if that fixes it.

[LHP]

Are you running extended screen/multy screen?

If you are, try running dcs on 1 screen at your normal resolution and see if the issue is still there, I found my glitches were caused by running an extended/multyscreen setup

 

If you want to read more here's what went through to find it, it may not be your issue but give it a try

 

 

[BIGNEWY]

Also in NVIDIA settings use Low Latency Mode - Ultra 

see if you see improvement 

[Flapjacks]

It ended up being the GPU. Just got my PC back today and FPS is 100+. I appreciate all the help folks!
