#Severe FPS drop (~5 FPS) when opening vconsole2 in custom game

While testing a custom game, I’ve encountered a severe performance issue related to vconsole2.
Issue: Opening vconsole2 during the hero pick phase instantly drops FPS from stable values down to ~5.

Details:
No errors in game scripts — all Panorama scripts have been verified.
vconsole2 itself shows no output or warnings at the time of the drop.
The issue occurs consistently and only when vconsole2 is active.

Questions:
Could this be related to pre-caching operations (as mentioned in previous discussions)?
Is this something that requires a fix on Valve’s end, or is there a workaround?

this seems to be related specifically to logging itself, not just VConsole, and i don't think there's much to be done

i tried connecting to dota logging port externally (anyone can do that in tools mode, it's on localhost:29000), and it prints thousands of messages per second, most of which are "lua is currently executing true false" and such, seems to be debug leftovers from Valve

iirc you can disable some type of messages on vconsole2, maybe it can help

vconsole filtering is done on vconsole side, and lag itself starts as soon as you connect to that socket - you don't even have to receive anything from it

#

outside of the vconsole that is

so the lag happens when you run the custom game?
I did try open doto tools just before and no lag experienced, but not opening any custom games

#

I suppose that makes sense if the lag is caused by the huge amount of log from lua engine
