1. Open VRChat
  2. Open your large VRC Menu
  3. [REQUIREMENT: 200, 500, 700 or 100 notifications, in this case, friend requests]
  4. Click the "Notifications" tab.
  5. Your game should buffer, proportionally to the amount of notifiactions and the time it takes for each notifiaction to load into memory. Time can vary:
PC:
200 Notifs - ~1 seconds freeze
500 notifs - ~2 seconds freeze
700 notifs - ~5 seconds freeze
1000 notifs - ~8 seconds freeze
(Phone -, relative to each phone's processor.)
Proposed solution would be buffering notifications in packets of 50's instead of all 700 or 1000 at once. I cannot count the amount of times I've ended up accidentally pressing the notification tab, greeted with the 'great freeze.'
Here is a clip on android phone of the "great freeze," I was currently standing at 730 notifiactions:
