NVidia users that suffering from stutters - check this out please

[msalama]

Right-o. Finally stumbled on something that _did_ help somewhat. Try turning off the driver's shader cache and see if it lessens stutters - did for me, even when said cache was on an SSD.

 

You need NVidia Inspector or similar to turn it off, though, because the vanilla driver UI won't let you. Anyway, be so kind and try this & report back please :)

Their is an option to turn off shader cache in nvidia control panel. Will give it a try

I have an Nvidia card but don't suffer from stutters. Are you sure this is peculiar to GeForce cards, or could it be something else?

Ah, it's there as well? Cool, thanks for pointing this out.

Not sure in the slightest TBH, but it helped ;) Shader caches get written to the disk, and disabling said disc I/O did alleviate some in my case. YMMV however...

[secret1962]

Just tested, nothing changed much.

 

EDIT: let me retest it though...

nvidia shader cache on for me, no issues with stutter at all, but was worth looking at msalama.

[msalama]

No, what I asked was folks who suffer from stutters to try this out, since it did help in my case. I.e. no need to try this if you're not ;)

[secret1962]

Nope, just retested and still getting micro stutters.

worded my reply wrong

 

I have the shader cache on with no stutter

 

it is worth looking at if you have stutters though, i.e it can not hurt to try

K :thumbup:

Hmmm, that would be exactly the opposite of what they says in the description of the control panel.

[msalama]

I know. Helped regardless.

[Tello]

Maybe it has something to do with your VRAM - I have very, very old CPU and only use 8GBRAM@1600mhz - But on my gfx I have 3gb ram and never really seen any stutter or low FPS. I can post my game-settings if you like.

[msalama]

and never really seen any stutter or low FPS

 

Thanks, but I don't think there's any need anymore. I reinstalled my graphics driver + tweaked the card and sim settings both - and to my amazement am as good as I was in v.1.5.2 now. I'll attach my current configs so y'all can take a look if you want (rename the NVI_DCS_CURRENT.txt to NVI_DCS_CURRENT.nip, though, or NVidia Inspector won't load it).

 

But a word of warning still: these settings are pretty rudimentary, so you'll definitely lose some eye candy if you decide to use them. But along with the driver reinstall, they did help me a lot regardless.

 

EDIT: Upped the settings a bit, still no stutters for me, the originals were pretty much unusable in a combat situation since you couldn't see ****. Please reload.

Which reminds me that there actually _was_ a previous v1.2 upgrade where this helped me as well. Was the same story then as now: upgraded DCS, got a lot of stutters, tore some hair off my head, tweaked, tweaked some more and then finally decided to reinstall the graphics driver. Result: a smooth-running sim again. So please, give that a try 'cuz you never know...

[msalama]

Oh, and one more thing. Get rid of the autoexec.cfg "affinity_mask = 12" thingy too while you're at it. Seems to cause more stutters than prevent them in v1.5.3. Or that's how it looks like at any rate.

[Jacks]

What does the affinitymask=12 do?

[Theskyline35]

Does it work for AMD User ?

[droopy114]

What does the affinitymask=12 do?

 

Tell the sim on wich CPU core it will run.

[kobac]

I have "affinity_mask = 12" in autoexec.cfg, and I don't have so many stutters when I play on servers that have less players. I therefore draw the conclusion this is more related to the CPU speed, amount of RAM and video RAM. When I play on a server that has a lot of players then to me occur freezing or even DCS crash. But I have only 8 GB RAM and an old GPU with 1GB VRAM, so I am limited FPS to 30 in order to avoid screen tearing.

[msalama]

related to the CPU speed, amount of RAM and video RAM.

 

4.6GHz / 16GB / 4GB

 

And in my case, it clearly did help. But one should bear in mind that no tweaks are applicable across the board since no two PCs are alike... so change, test & reiterate until you've found your sweet spot :thumbup:

4.6GHz / 16GB / 4GB

 

.....since no two PCs are alike... :

 

Indeed, took 7 Dell Optiplexes out of the box and ran them through Windows Updates....you could already see them differ...the more you work them the more they differ.

 

Redmond Style :(

 

I lately had an issue with my GFX driver, took me 2 days and a dozen NV installs to find the culprit. Things can be very simple but hard to detect.

[Wolf Rider]

What does the affinitymask=12 do?

 

sets the multicore CPU to just run the Sim on the first two cores ( 0 and 1 ) if Core Parking is left On, it may cause grief. Otherwise its of no real benefit for Operating Systems newer than Vista (It was of great benefit to Windows XP, though. As long as it was set to use cores 1, 2 and 3 - leaving Core 0 for the OP Sys' use)

[Badlego]

I also had very low fps sometimes and a great input lag. I found out, that Asus GPU Tweak ( i use it with my asus gtx 660 ti) sometimes set the gpu clock down in idle mode, even when DCS is running...this problem only occured with Win 10.

 

Well the simple solution for this problem was to reset the properties of asus gpu tweak when the fps dropped
