Talking about drivers, I ended up rolling back to a driver from last year (385.69) because one of the more recent drivers was causing roughly a 30 to 50% drop in fps across the board for me. It's almost as if Nvidia is intentionally trying to slow older gpus down more, to the point of frustrating you into buying a new one. Sort of like what Apple was doing with their phones...

Several articles have being made telling about this and NVidia is just ignoring to provide a proper fix!
I wonder if there is a fix like that for the Vulcan issues (I have never messed with Vulcan, so I don't know if it's possible or not).

Cross-positing from my thread. Exactly the same symptoms. Completely unrelated to mesh particles or particles. 1060.
Issue is a regression. Tested it in 4.15, works flawlessly.

A question thou: how can the issue disappear when rolling back driver version? I did as suggested at previous posts and the issue disappeared, at least looks like its gone. If its a memory leak related issue (it shouldn't have garbage collection at this point, since we talking about rendering thread) it must be at the render module or at the driver.

I can't say anything conclusive about the driver. I did not experience the issue anywhere else, including previous UE4 versions. I'm on 390.65
I've checked other 4.19 projects, I have access to. There is always something that triggers the stuttering, including stat command.
But with draws to render target blueprint it escalates exceptionally quickly.

Thanks!

Is filed incorrectly. It is not related to particles directly.
The hitching will be present in all projects, but certain features will make it onset and deteriorate much faster.
So might as well receive a bit more than some attention.
Reproduction steps:- 1) Download test project as provided.
- 2) Open with engine version 4.18.1
- 3) Open the Content/BugMap.umap
- 4) Play in standalone
- 5) Enable stat unitgraph
- 6) Measure
- 7) Wait 15 minutes
- 8) Measure
- 9) Open test project with engine version 4.19.0
- 10) Open the Content/BugMap.umap
- 11) Play in standalone
- 12) Enable stat unitgraph
- 13) Measure
- 14) Wait 15 minutes
- 15) Measure
- 16) Behold!
Stat unitgraph 4.18, after 15 minutes:
:
Stat unitgraph 4.19 after 15 minutes:
RhiCmd 4.18
RhiCmd 4.19
Kalvothe Might want to point, whoever will be looking at it, here:
What is wrong with CeateTileVerticesBuffersLegacyInit ? Why would it be called for drawing to render target anyway ? Not cool.

This one of the main reasons 4.19 is a show stop for me, followed by issues with Vulkan, reflections, all reported, can't use it as it is. Definitely will wait for 4.20 and don't bother with all the trouble this version brought to the table, I can't really expend all of my time figuring out why something stopped working or not working as intended, instead of carying of my own project issues which for now are still based in 4.17 (I know games launching are based on very early versions - like Sea of Thieves is 4.10, but c'mon...)

I don't have a clue though, why there are only a dozen of posts about it here. Not everyone is running editor/game long enough to notice ?

Personally I haven't made the jump to 4.19 yet since I've seen nothing but horror stories - and I've been unable to make an installed build since launch. Quite a lot of the rendering plumbing was changed for Temporal Upsampling I believe - it's quite possible all that rummaging around has caused some problems.Everything @ Stormtide Games - Snr Programmer @ Black Matter Pty.

What are the BEST Unreal Tutorials / Docs? There are none tbh... Here's why
Instead its better to just take projects apart (see the free 'creators' listed here)

Not saying its 4.10 all over again, but definitely seeing less random out-of-video-memory crashes, which is a relief.
I would not even know about the issue, if not random chatter on discord, because frankly saying I did not bother giving 4.19 a proper test for I was not intending to use it, other than for several my personal pet projects.

I was unable to repro the issue after extensive monitoring. Please provide additional information if you do believe this is a bug. Else I would I check your hardware to make sure it is suitable to provide the results you are looking for.
I am frankly in doubt, what additional information could I provide.
Would mean magnetic declination for place and time, when the issue occurred, be helpful ?
