Thank You Eagle Dynamics!

Just a quick shout out:

The current DCS-version is running blazingly fast on my system since the last update in VR!

I had a great time flying this morning

Thank you ED !

Yeah, I had great results flying the latest version today! I don't have the balls to try it again in case it starts stuttering again and framerates suck. I've had it happen before.

Just glad it ran really nicely for the first time in months.

EDIT: Oh yeah, loading times are a heck of a lot better now too!

Well, I ran the sim again last night and while the loading times are still much better, the stuttering is back again and framerates are starting to drop again.

Pardon my French, but <profanity> IT. It's been like this forever. It was running great, and now it's back to a stuttery mess with framerate drops.

Oh well, to hell with it.

Now, why don't you post your DCS.log? Maybe there's some clues in there? 

Cheers!

I've never been able to make arses or teakettles of the dcs.log, but here goes:

Thanks for any insights!

As a starting point since you only have 32GB RAM, I would adjust your pagefile to a fixed 32,768 MB on your fastest drive (it's currently only using 2,048 MB

I've tried all that, and my DCS missions don't use all 32 GB anyway. I also have 16 GB on the graphics card and usually only about 10 GB gets used, sometimes maybe ~12.

Besides, I've had it running great on my current system. No idea why I sometimes get it to run perfectly after an update, only to have it start stuttering and giving lower framerates the next time I run the sim.

My GAWD what a nuisance. At least they fixed the bug that gave dreadfully long mission loading times.

Why did you change jt back? DCS demands more and more resources, and even if it says it uses less, one should have the swap file at 32768MB like Rob says, if one has less than 64GB physical RAM. Solves lots of crashes. I can attest to as I have 32GB myself.

Yeah, that seems to be the minimum requirement these days, unless one wants lots of swapping.

I don't have problems with crashes. Can't remember the last time DCS crashed to desktop.

As for my 16 GB graphics card, I run a single 2560 x 1440 display and 16 GB seems plenty. I rarely use more than 10-12 GB at max, most games barely use 6 to 8.

Be that as it may. My system is 13 years old except for a second hand upgrade a couple of years ago to a 2080Ti, and I don't have any stuttering. My FPS is of course nothing to brag about, but it's over 30 and smooooooth. 2560x1600 60Hz. It only crashes when I OC the GPU or don't have a fixed swap file.

And yet there are people that throw a tantrum when the fps occasionally dip below 120 ....

Everyone has different tolerance levels to 'low fps'.

Hehe! I guess when 30FPS was the holy grail for Doom 2, some of was were "cured" for the foreseeable future.

Because it's not about your GPU RAM (more important in VR, but not always the issue), it's your actual RAM that's being influenced by your lack of SYSTEM RAM.  Yes, lack of SYSTEM RAM can cause crashes, but also stuttering.  Pagefile can help with that.  As a basic rule of thumb having a minimum of 64 GB physical RAM + pagefile is a good recommendation to avoid issues.

Well ... even with 64GB RAM (i9-14900K) + 16GB VRAM (RTX 4070 TiS) I still see stuttering sometimes. I never had any stutters with MSFS2024 with most graphic settings maxed out. May be the older graphics engine of DCS is coming to its limits?

I don't doubt the graphics engine is showing it's limits, but reality today is 32 GB isn't enough (esp. in VR and MP) if you're less than 64 GB without pagefile.  Having said that, MSFS is a very different game to DCS (I think people under-estimate the overhead of destructable units and proper simulation of weapons behaviour) so I'm not really sure you can directly compare.

[TheBiggerBass]

You are probably right. Don't get me wrong, I really don't want a DCS 3.0 passing such an awful beta testing period like MSFS2024 in the last 8 months (and still does partially).

Ok, I set my pagefile to 32768 MB as per recommendations.

I also found that DCS runs much smoother if I don't use Vsync either in the sim or in NVCP. Instead, I turn Vsync off in the sim and use Fast Sync in NVCP, then set the framerate I want (75 Hz for my HP Omen 32" monitor) in the sim using the slider. Runs MUCH smoother now.

For whatever reason, DCS doesn't seem to like Vsync very much. Fast Sync is much better.

Are you using Vsync, either in-sim or in the driver? Turn it off and use Fast Sync in the graphics driver (NVCP) instead, it eliminates screen tearing. Then set the framerate you want in-sim using the slider in the Settings menu.

Greatly reduced (just about eliminated) stutters for me. DCS doesn't seem to like Vsync very much.
