Constant Stuttering Frequence since yesterdays update

[ejbhimself]

i receive stuttering every few five or so seconds since yesterdays update, running exclusively in a self created training mission which worked perfectly fine before, so it's not any sort of my own shenanigans. i guess genuine techies - which i am not - reported this in depth, so i'm just here in order to express my hopes for a quick fix.

or should i turn back to the older version, since a fix is not in sight?

best regards.

I've experienced the same. Something has changed that is causing microstutters for me too. 

What I've found interesting is that I'm running on 72FPS, and get drops to 60FPS momentarily, and then back to 72FPS. 

If I change to 90FPS, I get 90FPS, and then drops down to around 78FPS momentarily for the stutters, and then back to 90FPS.

If I change to 120FPS... same thing. Drops down to may be 105 but then back to 120FPS. Each time it says "CPU Bound" but I don't believe it is a CPU being overworked, because if I can get 120FPS mostly, with the stutters down to 105FPS - why can't I get a constant 90FPS or 72FPS? 

I tried using a utility called RivaTuner by 3DGuru to lock my frame times in (72FPS for instance). This has significantly improved the stutters, but not eliminated them completely. I find if I set it to 68 - I can get consistent 68 without any stutters at all. Setting it to 72 still has me stuttering down below 68 though - so it's very strange.

I'm focused on these FPS rates as this is what my VR headset can set the refresh rate to. If you are on 2D, you might be able to reduce the FPS to whatever gets a consistent 'lock' with FPS. 

My CPU is running at 5.8Ghz. I can change this to 5.2Ghz and there's no noticeable difference. So it seems that it's not an issue of the CPU not being fast enough either. 

At a guess - it seems DCS isn't working well with interrupts, or some scheduling is causing some serious hiccups / interference within the main simulator thread. 

I don't believe multithread wasn't bedded down before they dropped single-thread, and had some issues. I'd say they're still playing under the hood with the multithreading stuff (which honestly - needs to be played with more anyway) - but this has triggered something negative with the latest version. 

Best you can do really is try the set of usuals:

• Verify core parking is disabled (Use Park Control)
• Try Process Lasso and use Sets to reserve P-Cores only for DCS
• Disable Tacview if installed
• Set windows Powerplan to Ultimate
• Try (after DCS has loaded) - going into task manager and disabling DCS access on Core 8 )

Yes, these are bandaid solutions, but until ED do something about this (and I don't expect anything significant to happen until Vulcan) - we need to do our bets to find workarounds.  

Hope one of these helps.

Drop your DCS log file (C:\Users\username\Saved Games\Logs\DCS\dcs.log) here so somebody can look at it and offer advice.

S!

This is how DCS looks with it´s built in metrics after latest updates. Before it ran buttersmooth. To test this one just go to Fw190A or any plane of that matter, select The Channel, Free flight and fly over the city at the coast looking to either side from cockpit.

for the ed-members: i wanted to rollback to the last update, but the command-box way doesn't work. i found this one here where an ed-staff member provided an easy rollback file, which i tried and worked for me, but of course, the version is not the last one, but way too old. if you could simply provide one for the last update, which would, in that case, be the last one for me to use every time until the problems get fixed - if ever -, this would be nice. thanks in advance.

@ejbhimself It's just a text batch file. Open it with notepad and type in any version number you need instead of that old one. You can quickly check all recent version numbers in update thread:
