Zhi-9b fps spikes

[Spectrium]

Chinese tranport chopper (Zhi-9b) has fps problem. It has FPS spikes every 3 seconds which screen is freezing for 0.2 sec in Qwai River map and some other maps(i don't know every map)

Not sure if the problem is about me or everyone have it.

This is a bug probably rather than feedback but yes, this is a problem for many people.

If the map has the big transheli like black gold or wanda shan, getting into one of those for 5-15 seconds will fix the FPS problem. For qwai, no help.

Sorry about topic channel. Just put it here while i was flying with zhi-9b. I forgot to open topics about problems after leaving the game(Actually i hang about it )

Actually if i don't remember wrong this started with the 1.2 patch. Before that patch Zhi-9b was a lovely chopper(it still is without that bug) And I think it is because of the dust effect of helicopter. I am not sure about it.

YES. Thank you for finding the vehicle name. It spikes because of the lights that flash on it every 3 second, and it makes it unflyable. I can not do CAS on black gold insurgency because of this bug.

Yea we know about this, but have no idea what causes it. It also seems to happen on the french Panther helicopter. That one is pretty much same as the Z9. If anyone has a clue what could cause this, please let us know.

That makes this bug even more mysterious

I believe the helicopters have navigation lights that flash every 3 seconds, causing a lag spike. This may be the problem.

This bug, also known as the "Merlin Lag" since it happened on the Merlin helicopter waay before the Zhi-9B, has no known cause and only happens for a few select players, and sometimes only on certain maps and not always all the time. What is even stranger is it dose not seem to affect the Zhi-9WA versions (the attack versions with weapons and if anyone dose have it on them please say) which are exactly the same as the Zhi-9B, other than they have more polies and load more textures, + have weapons and no/fewer passenger seats...

Nope, they where never in fact on the Zhi-9 series of choppers as I lead a small crusade with their implementation to have them removed from all aircraft in PR since aircraft in a warzone would never have their navigation lights turned on, for obvious reasons

The only effects on the chopper, other than its destruction effects are the e_exhaust_startup and the e_exhaust effects which it has two of each of them for the two exhausts. But saying that, after looking though a bunch of other choppers they don't seem to have this affect added to them so it might be that and possibly worth removing to see it helps, but nor dose the Merlin thou and the Zhi-9WA series also has it so ye, probably not

Clearing shaders fix's this bug. Maybe put an option in the launcher to automatically clear shaders on launch?

Have had it happen on Xiangshan AAS STD with Zhi-9WA with LGs.

Can't reproduce. Tried on Qwai, I was able to fly without lag spikes with Haitun. I've had this bug only once in Blackhawk, like 1.0? It was fixed in hotfix or something, iirc.

[doop-de-doo]

I apologize for necro-posting, but clearing cache doesn't solve it.

[PatrickLA_CA]

Can confirm, still have those spikes even after clearing cache.

Did remove all blank effect leftovers from helicopters, we'll see if they prevent FPS spikes.
