#Sudden drop in stream quality; from near perfect to unplayable.

Hello, I've recently installedd ALVR and it's working fine, but usually a minute in or even seconds in- the quality of my stream drops. There seems to be no obvious flaw with my computer, I'm using a CAT7 ethrnet cable straight to the same router that my quest 3 is connected to- on 7900xt and 5700x3d system- so nothing there. I've tried to diagnose the issue with a sudden drop in throughput from ~300Mbs to less than 1mb. Is there any solution to this? Im using a RT-AX3000 asus router.

#

I've noticed prior to the huge drop in connection, visual artifacts seem to appear around. I dont know if this correlates to anything.

using hevc instead of h264 can be more efficient

#

such a huge drop has to be some network issue

#

make sure router is not set to mixed mode

#

check if neighbours are turning on microwave or other interference

#

if some old device connects to your wifi it can cause this

supporting older standards

wan speed is not used, only lan speed

#

what you are checking here is not helpful

#

either your pc is not producing the frames anymore, or the network is dropping them

along with my phone being able to access youtube n such

none of this matters, as it uses little compared to playing demanding stuff

#

make sure your alvr is set to use hevc encoder

#

it indeed is

set to 90fps

does your headset have 120fps mode turned on?

#

what other settings did you use? should revert to defaults and use presets+hevc

#

show the statistics when quality drops - and mouseover it to show numbers

#

check if your pc is throttling

#

its a hidden option

#

sidequest can enable it

#

check on pc side - has to be either pc problem or network problem

#

mouseover the stats should tell why - if it says transport latency then blame network

#

network throughput goes from roughly 300mbps to <4mpbs in last then 3 seconds

#

I've fixed it now

#

After I switched to h264, every subsequent stream I've had now runs well beyond the first few seconds

#

HEVC seems to be the problem

should i limit it to <200?
