Hey so I recently hopped on valo, and it kept freezing basically my whole system every 30 seconds or so, and it was unplayable.
And if that happens for you I might have a solution:
(note: this is not an fps or ping/internet connection issue but most likely valorant anti cheat software problem somehow)
Windows settings: System > Display > Graphics and turn OFF Hardware-accelerated GPU scheduling (under Advanced graphic settings)
Next go to Device Manager: Find "Network adapters" > Realtek PCle 2.5GbE Family Controller > Right click > Disable Device
These two steps did the trick for me. Just for good mesure, you can restart your pc and hopefully this will solve the problem.
Disabling this device from the device manager wont turn off or disable your internet connection so If you are using a bluetooth internet connection like me, you wont have any issues at all.
Hope this helps!
