I really can't figure out why this affects the test so much, the processor i have should be enough powerfull to run this simple test, and also this Armoury Crate service takes just 2% of the CPU
That's average 2% CPU.
Just because it's 2%, doesn't mean it has moments of 100% surges (at least for a CPU core or few). Or perhaps it's a blocking port register read. Or perhaps it's a Ring 0 blocking behavior while it tries to realtime communicate to specific RGB registers (instead of a more friendly DPC system). Or some other thing. It simply averages out to 2%.
If it were 2% in a fairly constant way, then definitely won't interfere with TestUFO. But it's literally a ultra-high-priority (like REALTIME) brief spikes to 100% of at least 1 CPU core. In other words, it seems Armory Crate briefly surges to 100% CPU for a millisecond or two -- those spikes. It just simply averages out to 2%
Such high-priority surgey behaviors by utilities, is BAD.
Even 1ms CPU surge to 100% can eat away 50% of a 500hz refresh cycle!
This isn't important for 60Hz gamers. But important for 500Hz.
That's enough to add videogame lag.
That's enough to stutter TestUFO.
The creator of Armory Crate needs to fix their bug
The developer and QA testers of Armory Crate needs to put 500Hz monitors in their QA test fleet
Please tell them. Thank you. The more BlurBusters fans complain to Armory Crate, the merrier. RGB software CPU usage is a plague in the 500Hz era. No wonder Microsoft is taking over.
