@LumpyCustard Could be 2 things, 1: you have cloth physics on, clothes in this game seem to render when another player enters an imaginary circle that surrounds you, when they enter it the game engine has to simulate them, strangely though this seems to cause an stutter(when at the beginning it was supposed to reduce performance hits caused by the clothes physics simulation). now, once they enter the circle their clothes will be rendered at least 3 to 4 or more times your circle's radio(tested by me). now i believe the stutter itself can be caused by two things, 1: possible bad optimization of the physics assets for the skeleton causing such a high load on the cpu that the cpu won't even try to keep up and as result will generate a huge 100+ ms frametime spike which we will perceive as very annoying a stutter. 2: maybe they just need to increase the cloth physics assets render distance while reducing the quality at longer distances so that once the cpu renders them it's all good and it possibly will reduce or eliminate stuttering. now the other more probable cause of your fps problems is that your 980ti is running out of vram at that resolution, some time ago i was playing taiga at 1080p and i was getting 5,7gb of vram consumed.
oh and by the way, recent patches did indeed reduce performance. i don't see why though.

@recurf low fps on high player counts is due to a cpu bottleneck, D3D11 doesn't scale as well with a multicore cpu as D3D12 does. i wish they released this game on a more modern api.

What's wrong with the cloth physics assets? maybe too much polygons, there gotta be something with them, since when i turn them off my frametime graph becomes buttery stable. not a hardware problem. Are devs even looking into this?
By the way, anybody that enters this post and has this problem please comment back saying that you have it, so that this thread gets more attention.

Crossposting from another thread about cloth physics.

@Bear264 said:
I made sure all of the console stuff was in order, and tested this with a friend (he also has a 1070). and here is what we found

the cloth physics only turn on when you get close and then look away
then when you back away the physics turn off

It looks to me like the only thing that isn't working as intended is the looking away part. It's worth noting not all cloth items do this.
It seems "crude plate skirt" is working as intended but "longskirt divided" is not.

EDIT: this test was done in deathmatch. Playing in frontline it looks like all cloth physics are off except for my own regardless of looking away or not, and cloth items.

EDIT 2: playing a bit more in frontline and paying closer attention, I was able to get some of the cloth items physics working with the look away method, some of the cloth items flat out didn't work, and only the "crude plate skirt" seemed to be working.

It looks like cloth physics aren't functioning as intended over all. I have a pretty high end system and cloth physics and performance are really inconsistent for me when I have them turned on.

it seems that it was just like you show on your video, cloth physics seem to render within a radius of maybe 30-60m (with all else on ultra). funny, i never actually noticed that cloth phyisics stopped being rendered that close. is this low render distance intended or is it in our side?

that's some really interesting info @Bear264 i'll go and see if the same happens to me, but as a far as i know cloth physics always rendered well(at least on my pc).

Well i tried what you said in it did help a lot with cloth physics on, it seemed to reduce stutter frequency by about 66%. keep in mind that this could just simply be placebo on my part, so i am not really sure if it really did something. we definitely need an in-game benchmark. I shouldn't worry about this too much since with cloth physics off and everything else on ultra i can play the game 100% stutter free but i really love cloth physics. We definitely need an UE4 dev or a mordhau dev to explain to us what is really going on with cloth physics.

I'm no expert, but I have a slight suspicion that PhysX being disabled in the ingame config files has something to do with the issue. See for yourself in SteamLibrary\steamapps\common\Mordhau\Engine\Config\BaseEngine.cfg

You'll find the line:
bDisablePhysXHardwareSupport=True

As an NVIDIA user, setting that to False improved my performance noticeably. Let me know if it does the same for you - or if it causes any issues for you - there must be some reason it was off in the first place.
Good, i am happy to see that someone replied. thank you for your advice, i'll try that. i've heard that Epic had a bias towards nvidia and as result UE4 generally performs better on nvidia cards. not to mention that until december of last year physx was nvidia only. But as i mentioned before both( amd user and nvidia users) seems to have the same problem.

I just wanted to report this problem. it happens to me(RX 580 8gb) even when i have 100+ fps. but when i disable it, there is no more stuttering. i proved this by seeing how my frametimes graph fluctuated. for instance my frametimes were at 8.6 ms then they jump to 32+ms(and then they go back to the previous frametime) which is a stutter. but once i deactivated(cloth physics) my frametimes where 100% stable both while playing with unlocked framerate and locked framete(60 fps) 16.6 ms frametimes.
I am not the only victim of this problem. i've seen people with 1080ti gpu's(and 8700k intel cpus) and more nvidia( and amd cards) having the same problem. soon i'll post those here (as evidence). if someone(player or dev) is interested in seeing this in action just ask me and i'll make a video showing the problem stated above(with realtime frametime graph). Even if a dev doesn't show up here i'd like to ask someone who has experience with this engine(UE4) or clothing physics in general. what do you think is causing this problem?(certainly not hardware, given the fact that i experience this even when i have 100+ fps). More information: when the stuttering happens it'll present itself as a drop of 2 frames(or less) but given that the frametimes drop so low it feels like a drop to the 10-15 fps. If you or anyone you know is having stuttering problems in this game tell them to turn off cloth physics and test if it works. it certainly won't work for everyone but for a bunch of people it will. Again this is not that much of a problem for me since like i stated before, deactivating that option completely fixed stutters. but i really love cloth physics.
