Nope that is not the issue, it's turning on the TGP that does the most stuttering, way before pulling the trigger or anything sound related...

I agree with everything stated above, except that the GPU ram and system ram are used +- 50% so not the issue here...

chardly38 I have a thread were I am investigating this issue : https://forums.eagle.ru/showthread.php?t=201162 'change your computer' is an easy answer, from my perspective it's more like : - if you have low fps, that's fine but should be smooth / consistent - the same plane, the same map, the same graphic settings should give a similar performance between 2.2 and 2.5 IMO, but it does not. - We are in BETA release, so let's helpl the devs and ourselve by hammering at these issues till they are ironed out! One thing that seems to stand out between the stutters / no stutters camp is 16GB ram vs 32Gb ram, still investigating...

I'm investigating the general stuttering issue in another thread, a pattern seems to be emerging : - 16GB ram -> stutters - 32GB ram -> no stutters Can anyone on this thread validate or not this hypothesis?

Agreed, and if you turn vsync on you should be around 50-60% GPU usage...

I am not alone in this madness it seems :crazy: I've been playing around with graphic settings, windowed vs fullscreen, vsync, nvidia cp and profiler. I have yet to find a single culprit, like Solid84 says I can make it 'better' but not disappear. Some options that seem to have a big impact on stutters and TGP usage : - Dirt & flare - Depth of field - Shadows (any amount) There are some of us which do not have this problem it seems... The only thing I can think of at this point if 16Gb vs 32Gb RAM : Stutters (16Gb RAM) : - KCferrari - Solid84 - (me) No stutters (32Gb RAM) : - HiJack - tintifaxl I'm grasping at straws here... RAM usage is around 50% at 16Gb so I don't see why this could be an issue. Gentlemen HiJack & tintifaxl, would one of you be so kind as to try to replicate the problem on you rig with 16Gb only?

I did try in NVidia control panel Negative LOD detail to 'clamp', it seems a little bit better now but not perfect.

hey Tumbler I'm checking your system specs and my first intuition is that it is nit a problem with the performance of each individual components as dcs 1.5 and 2.2 would run butter smooth on a machine way less performant than you have. 2.5 is another matter, as I am investigating in this thread: https://forums.eagle.ru/showthread.php?t=201162 A few questions come to mind: - do you overclock?, does throttling back the overclock change the stuttering? - you seem to have this problem from'day zero', or did it work correclty at the begining and got worse? - maybe it's something mundane like a bombed windows, do you have a spare hdd to try a mint new windows install?

Right, then the 'minimum system requirements' would be more than 16gb ram since without it the game crashes, how would that look to potential buyers?

HiJack you are using a Radeon GPU, you do not have this issue?

Thank you for the suggestion HiJack, however it is unrelated to graphic settings as stated above, and just to be explicit I did try with the following : - MSAA none - Defered shading OFF - Preload, trees and smoke to minimum - HDR OFF - Shadows OFF - Ground shadows OFF The stuttering persists as described prior... I also cleared shaders and fxo folders, never imported graphic options from alpha or 1.5. Granted the only thing I did not try turning Off is reshade, as I don't see how it could be related. I will nevertheless try with Reshade off just to be sure.

Yep same here

Yesterday I tested quite a bit and concluded the following: - stuttering not related to graphic options, the only option I didn't try was lowering the resolution, but i'm just at 1080p... - not related to map, I have the same behavior in Caucasus and Nevada - not related to multiple monitor usage or sensors exports - does not seem processor saturation is an issue - does not seem gpu saturation is an issue When I say 'does not seem' I mean the different cpu and gpu monitors are maybe not recording transient saturation if it last just a few milliseconds Aggravating factors in no particular order: - flying close to other units, air, ground, friendlies and enemies alike (all ai though) - flying close to structures that you could collide with - flying through smoke - using sensors (TGP, MAV, CCIP) One factors stand out alot, it's using the TGP, that will slice off up to 10 fps when combined with other factors above. Another odd thing I tried is this: I maxed out all graphic options just for kicks. The fps meter was showing 40-45 fps but the stuttering was so severe that it looked more like 5-10 jittery fps!!! Still BETA testing :smilewink:

Well from all your comments (I dont play online...yet!) it seems 2.5 OB is leaking like grandma at a christmas party :music_whistling: Having been on the developper side myself for other softwares, I guess it's why it is still classified a BETA and not the final release... Memory leaking is one of those housecleaning tasks that need to be ironed out before the final release. I'm sure somebody at ED is carefully reading our threads, it just would not make sense to answer now because, well, we're all beta testers now!

awesome! :thumbup:

Happy for you you cleared it up! So it was Windows after all :doh: Many pilots are reporting stuttering in 2.5 under various circumstances, I guess there's still some ironing out to do.

Did you try a manual repair? https://forums.eagle.ru/showthread.php?t=114030

C'mon guys and gals! Why so impatient? I've been waiting since 1986, the Tomcat is my childhood fantasy. Ever since watching Top Gun when I was too young to remember anything else I've been obsessed by this plane, literally dreaming about it. When it comes out, I want it to be perfect. It's like trying to seduce a very beautiful women, take it slow, lay back, be confident. One day she'll be yours.

Did some more testing this morning: Map is Caucasus instant action easy spring, multiple passes at waypoint 2 (first target) pass 1, gun strafe, no tgp - no noticeable stutter Between passes, turned on tgp - one time stutter, big momentary bump in cpu usage Pass 2, ccip rockets - light stutter when overflying target (very close to groud) between passes, standby tgp Pass 3, ccip rockets - again some stutter when overflying (smoke from the marker and destroyed trucks an issue?) Not a very scientific analysis, but so far my gut feeling is that the stutter seems to be aggravated by any combination of these factors: - overflying ground targets (ai cpu usage?) - smoke from markers and burnt targets (gpu usage?) - tgp on (gpu and cpu usage?) i have some screenshot that i need to analyse in hope of finding more correlation, i'll post later this evening.

Maybe unrelated, maybe not... I'm getting black squares on the TAD in the A10-C, I posted it as related to a stuttering issue on this thread : https://forums.eagle.ru/showthread.php?t=201162

I cannot see how it would be processor related... As far as I know you cannot 'update' processor drivers in windows, since windows 3.1 I never saw any issue with processor drivers. One possible issue is that windows would become 'unlicensed' because of an important system change, but I'm running an unlicensed windows 10 and see no performance problems. But of course I could be wrong. Windows never ceases to amaze me even after all these years :glare: If you open task manager and check cpu usage, is it maxed out? I guess it should be no more than 50% for all cores. Thrashed video drivers could definitely be it, did it fix your problem?

Is it only me? I'm flying around in caucasus with the ol A10-C and getting a solid 60-80 fps from buzzing trees to the stratosphere. no problem there! I then felt like pounding something, so instead of just flying around I turn on the arm controls and the TGP and get ready for some death dealing. However, I start getting serious stuttering issues and it seems like it's from doing something related to engaging enemies (TGP screen perhaps) Stuttering gets worse when flying low around the targets. It kind of breaks 'the mood' if you get my meaning... Another thing that baffles me is there are huge black squares on the TAD like parts of the TAD maps are missing, duh? BTW check my sig I'm runing Ikarus touchscreen cockpit with exported TAD, TGP and RWR. With Ikarus off there doesn't seem to correct the problem so I'm still trying to isolate the condition that causes this. Anybody else got this?

Well... I'm a developper since late 1980's and I though chrisofsweden's comment made much sense, so aairon please expand your thought since it looks so clear to you that it is not a memory leak issue. From wikipedia (I know I know...) In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations[1] in such a way that memory which is no longer needed is not released.

True that... 'wetware' has a mind of it's own :smilewink: bit more complicated that hitting the reload button. I've been flying the A10 for about 6 months now, can lay metal down pretty good but still having problems with SAM threats. That's what I like about DCS, you never stop learning!

Well I finally found the time to get on board with the community (wife and kids permitting) so I just wanted to reach out and say hi!
