fps drops while braking

[pppet]

Hello,

Question for the community, every time I brake near the surfaces I have a short fps drop (see screenshots) which is really annoying in VR. Do you happen to have that too? or do you know a solution to this. I don't even want to talk about the random jerks that feel like reload jerks after I've been trying everything to stop them for two weeks.

thank you, greetings pppet

sorry for the supposedly bad English, it's from a translator

I'm not 100% if I'm talking about the same thing, but there is a short drop in fps when I come out of glide.

I get occasional frametime spikes from terrain or POI generation, but not from reducing speed while flying over terrain.

sry that I'm just getting in touch now.
I ran an extensive memory test (10.5 hours) to finally rule out the memory.
This is reproducible if I reach at least ~100 speed or more and set the throttle control to 0
This evening I will make a short video to make it clear.


Another topic is what I call hiccup problems.

What I have already done (no chronological order) regarding the jerking that I even do in empty space (occasionally) and near the surface (sometimes more, sometimes less):
Hags on/off
Game mode on/off
Game bar turned off
Gamepresencewriter disabled
Driver installed according to Morbad instructions.
Likewise the BAR according to Morbad instructions.
Shader cache cleared. ProcessLasso
MsiUtilityV3
PowerSettingsExplorer
Vsync on/off
Fps limit on/off
Reduce Settings (nothing changed)
Change Settings (tried various settings)
Reduce Resolution (nothing changed)
Reduce FPS (72hz) (nothing changed)
deactivation of all monitoring software

lastly yours
Shared folder disabled to rule this out too.

and much more(countless changes), especially on the Win10 side.


All temperatures and voltages are in the green range, so they are really far away from the limits.

According to the openxr toolkit, the stutters always come from the CPU:
in empty Space at 65-70 Headroom
on surfaces ~ 35-40 HR out of nowhere and feel like something is being reloaded.
Of course there are occasional drops on the GPU side, but the ratio is estimated at 1:30 and these can actually be influenced with the settings.

In addition to the GPU, the Samsung 970 Evo Plus is the only PCIE device in the system, half full and, according to Samsung Magican, 100% in shape
Two more SATA SSDs are also still in the system. Should I disconnect this to test?

With a lot of changes I thought that was it, and the next day there were jerks again, far less than before, but they are just there and driving me crazy. In 2D they don't bother me at all, but VR is VR and I don't want to play on the flat screen.

By the way, I already had this with the 6900XT and blamed it on the lack of performance.
And maybe it's my imagination that it's worse on planets with more red surfaces than on others.
it is better on some days and worse on others. It could have something to do with the network connection to the servers.

I had annoying stutters generally in VR, not really bad by really annoying.
I was using Quest 3 with Wifi connection to my 5GHz router with OpenComposite and OpenXR Toolkit ie not Steam VR + Virtual Desktop ie not Oculus Link.
I added a dedicated cabled to main router TP-Link AX3000 Dual Band Wi-Fi 6 Range Extender and connected my Quest 3 to that.
No more stuttering.

I also have the same configuration with ASUS RT-AX57 as a dedicated router @ 2401mbit (1m distance, quest3 as solo client) connection with h264+ 500mbit.
This works wonderfully, everything is buttery smooth without stuttering.

but as described above, it is already visible in the openxr toolkit overlay that the cpu is obviously having hiccups and since it also happens in 2D, it's just not that obvious and it's almost imperceptible.

EDO has occasional CPU-limited hiccups on almost every processor. They can be brute forced, to a degree, but not eliminated because the underlying problem is the game.

Have you tried adjusting the terrain work slider? Having the right setting can mitigate some performance issues with terrain rendering. I use 75-100% on most all of my systems, with my RTX 4090 liking ~85%.

 

[Morbad]

This is 2D, with a pile of custom settings:

I get that massive 200ms spike every couple of minutes while flying fast over the surface of most worlds. I assume it's a new large terrain tile being generated/loaded in, but that's mostly a guess. I'll probably mess with my WorkPerFrame and BlendTargetsResolution settings to see if I can soften that up without having to reduce terrain texture resolution, but I will drop back down to 8k if necessary.

In both of those captures, I do slow down near the end, from ~300m/s to zero. There is a tiny spike, possibly as the terrain renderer adjust to the changing rate of terrain generation, but it doesn't even reach 20ms.

I've now tested the energy saving plans and with bitsum highest performance the drop in braking (120>111FPS) is the lowest, with energy saving (120>93fps) the highest, which was to be expected.

OK, thanks, I'll test that thoroughly

so to close the thread.
I can't seem to get rid of the mini-stutters when braking, and apparently I've gotten used to it because it's to be expected.
I seem to have gotten the random hiccups under control now. I deleted every shader cash I could find and it's clearly better now.
