Fixing sluggish controls in Red Dead Redemption 2?
Riding through Saint Denis, I noticed this subtle but annoying gap between pressing a key and the action happening. On a 6400MHz kit, this is just weird. A latency tester showed the default secondary timings on the Asgard Snow kit were way too loose, with access latency swinging between 72ns - 80ns. I tried Windows Game Mode, but that did absolutely nothing. I had to go into the BIOS and crush tRCD and tRP from 32-32 down to 28-28, and set tRFC to 440. Latency immediately dropped to 62ns - 66ns, and the game finally felt 'snappy'. I did have a random reboot 10 minutes into the game during my first attempt, which I fixed by bumping voltage from 1.35V to 1.38V. RAM temps sat at 48℃ - 54℃ and VRM temps were 60℃ - 65℃. Fans were humming at 1400 - 1600 RPM. It took some trial and error, but the input lag is gone.
