[FIX] How stop crashes and poor performance with STEAMVR [FIX}

[WhIteDragem]

Turn OFF "Motion Smoothing"

there is a bug that generates 100megabytes of 'memory leak' per second

I toyed with and tested this for a couple of days. (so many branches of SteamVR, and driver installs, and Uninstalls of games/front ends and ....)

at the end of all the testing one thing had become clear...

whilst the SteamVR app itself doesn't show the 100megabytes per second link.
as soon as a game starts, there IS a 100megabytes per second memory leak.

one would tink the game has the leak,.. but fortunately I crashed out the SteamVR frontend at one point, during testing, and could see that all the games that *HAD* a 100 megabytes per second memory leak, no longer did.

Anyhow- long story mad short.. turn off motion smoothing in SteamVR settings (either globally or on a per game basis)

symptoms:
I had a locked pagefile.. so I could watch the RAM run out at which point the game would crash. The working set for the game would then clear from my GIANT pagefile/RAM pool.
Then when I closed SteamVR, the 'leaked data would clear' (In my case this was now 88GB of RAM... Depending on your pagefile size, your game might close reliably, after 6-16minutes..

For users using the standard 'windows managed pagefile'; this is likely to not really reveal itself on 'Quest ports', but on games that are 'cutting edge' and lean on the whole system (eg RAM/CPU/pagefile and CPU) - the result would no doubt be 'horrible performance'

so either 'poor performance' or game crashing; solved.. just turn off motion smoothing.

And please flood steam support with messages to tell them to fix their 'jank'.

Attention: Steam support; please fix your 100megabytes per second memory leak that occurs when 'motion smoothing' is switched ON.



....thats all folks.

I do not see this setting?

[WhIteDragem]

correct; and hence why it is an issue for many.

once the game loads, using the steam front end, you can open up the video settings for the game (on a per title basis)..
top option: Motion Smoothing. [set to OFF]

I literally forgot where I had set it, .. and then freaked out when the memory leak fix was to turn it off.. (sent an URGENT message to Survios, in an attempt to overtake 'follow ups on the issue' going direct to relevant team members)..

Then I figured.. "han on.."; "I HAD turned it off,.." and thought.. maybe it was removed with 1.07.. then I remembered.. "nah.. another screen"


I will give super short video showing "how to"

(also shows how to identify the memory leak; with a linked video at the end that explains the hows and whys of what such a 'system bomb' can lead to at a performance level)

-success to you! hope this helps
