Are you running the sensor in a USB hub? Might be the cause if so. Plug directly into the motherboard to see, or even on a front panel USB port. If you can't. Try removing some of these peripherals out of that hub to see if it gets better. It might be a case of saturating the connection too much and then producing the poor bandwidth.

Try keeping the TrackIR open as a window in the background. The window where you see the calibration globe. Leave it open and see if it gets better. It has happened to be randomly in a mission and this was the workaround. It proceeds to be smooth later after being open. If it fixes. There is something else going on. Don't run DCS as admin. Don't run TrackIR as admin.

Not volumetric. All of them have 2D particles that follows the rendering POV axis of roll. See bellow each individual textures. This is a tech that precedes 6 degrees of freedom cameras. Rally games and racing games in general behaves the same. We just see this in DCS often because we can look down on it and roll our pilots heads. Volumetric particles are expensive. Missile smoke also is 2D and it shifts between two modes depending on the FOV. I'm not sure if the secondary is volumetric or not. (it is very smooth in apearance).

Alright, thanks!

Yes. I know that very well. But notice those aren't "mods". I haven't introduced any modified DCS file. Those are simply unit packs inside the saved games DCS folder. No integrity check can detect addons like those. I pass on any IC on any server. I realize the 'mod' folder they are installed. I'm just puzzled on how they are messing with the Encyclopedia. I always thought the A-4 was innocuous addon, as well as the CH packs. I only have the Russian and the USA pack from CH.

Strange. I don't have any mods for the Viper, but only the A-4 and a couple of Currenthill unit packs and the Viper Block 50 won't show on encyclopedia on my side either. How come unit addons messes up with the encyclopedia that much?

If it was working dynamically as intended before, it is indeed a bug.

Highly depends on the method to take the readings. See the website I linked for. The method you took was maybe with averaged values. I yanked it hard to get the maximum of 145hz. Usually it read on the 100s to 110s hz. Either way I don't think it is the mouse.

I have the same mouse as a backup stored in a closet . I tested it in DCS a while ago, it is flawless. It is a very smooth mouse over a proper surface. Some sites says it has a polling rate of just 125hz. https://www.flipkart.com/logitech-m90-corded-mouse-wired-ambidextrous-optical-gaming/p/itm9f5e3227d7082 It is actually sealed in a box, the previous one I gave it to someone else: I opened it up and tested on this site : https://cpstest.org/polling-rate-test/ I gave me a max of just 145hz of polling rate while moving it around. It might be not too helpful as I run a setup at 40 fps locked for personal reason but I ran your P-51 track and found zero stutter when your POV moved around. I wanted to share because I recorded it and uploaded it at a good quality for you to see and compare. Another person can quickly confirm if your track is smooth at high refresh rates. Something seems to be related to rendering on your PC instead of input.

Weather system overhaul with better clouds. (I know it won't happen, I'm just a bit tired by the current one).

[I deleted my own comment not to derail the thread.] I'll happy to see more life into units especially ground units any day in DCS. I consider a bit too lean at the moment especially for flying helis.

I think it was just the wording, my bad. "The rendering is dependent on the machine that replays the track." No?

The word is not "rendered" for that. His PC is 100% rendering the scene. Some of the simulation however is not being calculated when repaying a track. 100% agree. If it is happening on shooters as OP pointed out, something off is going on in OPs side. Those are GPU heavy games right? I know RDR2 well, idk about LotF. Have you overclocked your CPU or RAM...or GPU? If so, undo it all and try DCS again.

I agree with this. Either way, here is a SU25T track with looking around. Low Flying SU25T.trk
