TrackIR stutters after update 2.9.8.1107 and 2.9.8.1214

[Miro]

FPS are fine, maybe a little less, but this trackir stuttering when turning the head is frustrating, I had perfect fluidity before. You can't see it on the graph under CTRL+Pause, and it's not constant, only from time to time. Maybe it's Phantom's fault, but it seems to me that I also have slight bursts in tactical commander. I tried everything (except windows reinstall), and I've run out of ideas what to do next. Maybye it's not trackir but game stutters, don't know.

since you are not sure if TIR is the issue, i suggest turning it off and testing. make a mission that you can use to test with. with and without TIR. i just updated to the latest version of TIR and have no issues ATM.

also looking at your log and the graphics settings. below is a comparison with my settings annotating which may cause performance issues. bolded are the settings and red font indicates my settings.

added graphics settings comparison; no such thing as SLAA :)

Thanks for Your reply @silverdevil I don't think it's TIR's fault, because it works perfectly in other titles. I rather think that it is the fault of some MT corrections that ED introduced in the patch. What I've figured out so far: Reducing the amount of ground units in my mission helped improve the stuttering when looking around, but it's not a solution to flying around an empty map. Before the 2.9.8.1107 patch it was running smoothly with 500+ ground units spread out along the front lines, now it's less than 200.

But most importantly, the second solution, which if I confirm, may be a temporary solution until next patch: Disabling HT in BIOS, I think this has temporarily solved my problem, but I still need to do some stress tests. So far, so good...

good to hear you are good. i have seen this mentioned in other posts.
