Aluminum Donkey Posted February 11, 2018 Share Posted February 11, 2018 2.5 here, recently installed on an uber-fast 960 EVO M.2 drive. Still have stuttering while flying. I was wondering if adding another 16GB of RAM, for 32GB total, would cure it, but... in my own experience, NOTHING cures it. I currently have my pagefile.sys on the SATA SSD, 24GB pagefile. No improvement. Any cure? Done the whole delete shader cache thing, newest video drivers... no improvement. People with GTX 1080 Ti cards and lots of RAM, and whopping LGA2011 CPUs post their vids on Youtube, and still have stutters. Seems like even the almighty 2.5 has *serious* programming shortcomings.

Mr_sukebe Posted February 11, 2018 Share Posted February 11, 2018 I was suffering from stuttering. Another forum member recommended a few ideas, and they seem to have resolved most of mine: - Delete the folders FXO and Metashaders from your User/Saved Games/DCS.openbeta folder - Disable MSI Afterburner, or at least change the refresh monitoring time from 1000ms to 60k System: 9700, 64GB DDR4, 2070S, NVME2, Rift S, Jetseat, Thrustmaster F18 grip, VPC T50 stick base and throttle, CH Throttle, MFG crosswinds, custom button box, Logitech G502 and Marble mouse.

NorgeNate Posted February 11, 2018 Share Posted February 11, 2018 Turning off my network adapter (WiFi) fixed my stutters but I don't know if that would apply to everyone.

fierceBeaver Posted February 11, 2018 Share Posted February 11, 2018 (edited) You can try nvidia 385.69 drivers. Many users tend to have less stutter with them. You can move your pagefile to ssd, buy some RAM(i know right;) ) and turn down some settings, try lowest first to check if your setup can handle lowest without stutter and go from there. Watch out for preload setting EDIT: don't mess with affinity please, there's no magic affinity trick - it will mess your setup. Just turn off unneeded processes (check it with ctrl+shift+esc and cleanup your mess if something works too much there. Don't kill important services just unneeded ones) Edited February 11, 2018 by soundslikerust Link to comment Share on other sites More sharing options...
hansangb Posted February 11, 2018 Share Posted February 11, 2018 Turning off my network adapter (WiFi) fixed my stutters but I don't know if that would apply to everyone. It seems there are many different fixes for it and not many ideas for the root cause. Others have reported muting the microphone helps. Whether it's network activity or mic activity, it probably means that the CPU is busing doing something else and causing DCS to stutter. Eliminating these distractions for CPU helps, I'm sure. As does assigning affinity, or moving other tasks off of physical cores with process lasso. It may also be why it helps others not but everyone. hsb HW Spec in Spoiler --- i7-10700K Direct-To-Die/OC'ed to 5.1GHz, MSI Z490 MB, 32GB DDR4 3200MHz, EVGA 2080 Ti FTW3, NVMe+SSD, Win 10 x64 Pro, MFG, Warthog, TM MFDs, Komodo Huey set, Rverbe G1 Link to comment Share on other sites More sharing options...

bolt69 Posted February 12, 2018 Share Posted February 12, 2018 Hello Guys, I am suffering the same stuttering problem and a guy posted a trick that fixed the issue (at least for some people). Some of you have probably installed the game on a SDD HD. Good choice I would say BUT it seems important to move the C:\Users\'user's name'\Saved Games folder to the SDD as well. So, here is the procedure to move this Saved Game folder : - create a new saved game folder on your SSD - go to the folder that hold your current Saved Game folder (normally, this is C:\Users\'user's name'\) - Make a right clic on Saved Folder and select properties - there is a tab called location, select it -in this location tab, clic on Move and select the folder you created on your SSD. Windows will manage to move the files. That's it. I hope it will help. Thanks to Icemaker/C6 for the trick !! Link to comment Share on other sites More sharing options...

AD Turn lowest settings possible, ALT-TAB to windows, run process explorer. Turn on GPU tab, Network tab, disk tabs to find what's your system is doing (click on the tab to make it in descending order). You can move settings folder to ssd like some other guy said (it won't help much), moving pagefile to SSD is good also. DO not keep your disks at almost full. RAM helps coz You can turn pagefile to smallest possible (just don't turn it off because some processes could start to behave strangely looking for it and slowing down your system) and DCS has some memory leaks also. But RAM is pricey. It won't help with stutter from other processes tho - you have to use process explorer for that. Just find what is working while you play and verify if you can uninstall or turn it off. It doesn't have to use 30% of CPU it can be 2% and be the cause. Remember your CPU doesn't have to be utilized 100%. It just will not make it in frame time. Try NVIDIA 385.69 drivers because it's known some new drivers are not slower but has little less frame time consistency.:thumbup: Edited February 12, 2018 by soundslikerust Link to comment Share on other sites More sharing options...

Looks kinda cool to play with :) This should let me know wazzup. I also installed 385.69 Nvidia driver... tried it, doesn't seem to make any difference really. But, I'll use it for now, since re-installing the latest one is a bit of a pain :) I currently have a 24GB pagefile on my regular SATA SSD. It hasn't helped any, so I'll probably just move it back to a mechanical hard disk. As I said, DCS itself is running off my ultra-fast 960 EVO M.2 drive (250GB capacity), which is what I bought it for :) The M.2 SSD is just under half full, so no problems there. Lots of room for more DCS stuff if I can sort this out (F/A-18C and Hormuz... Mmmmm!) Thanks for all the help everyone, I'd REALLY like to sort this out so I can just enjoy the damn sim, but although I'm not a coder, I have a gut feeling that it's a shortcoming in how the DCS simulation engine itself is written. Everyone seems to have this problem, even though quite a few people are rocking the Ultra-Uber-Hyper-Mega-PC-of-the-Gods with more memory than a human brain, liquid helium cooled uber-CPUs and half a dozen Titans in SLI and all that crazy jive, they STILL get stuttering--and in technical terms, that's just beyond lameass. If your gaming PC costs almost as much as a real fighter jet, there's just no excuse for it. Hopefull we'll all (Hear me, ED? Huh? Huh? Huh eh?!

We have the new Caucasus map. That's great for now. Enough already, time to FIX STUFF!!! I'm still trying to get a handle on what's causing the stuttering, and as much as I love ED's content-related work, I've just about had enough of all this and wish I could just "game" instead of trying to "diagnose". If people with computers that cost more than my internal organs are worth on the black market can't get a handle on it, then it's not a problem than can be solved by throwing more money/hardware at it.

There's a substantial difference between 385.69 drivers, and the latest ones (I just installed 390.77). The newest ones have better colors. I'm not just making it up; I had a good look at the older vs. newer drivers and the newer ones do a better job of rendering the full color spectrum. Everything looks better, the old ones had a 'washed out' look to them, kind of like a TN panel :) Just for the record, I *did* remember to set my monitor to 10-bit color depth.
