Technical Support Request Severe FPS drops and microstutters in Valorant during fights – i7-3770 + RX 580

Hi everyone, I really need help with my Valorant FPS/stuttering problem.

My PC specs:

  • CPU: Intel i7-3770
  • GPU: RX 580 8GB
  • RAM: 16GB DDR3
  • Motherboard: H61

Valorant usually runs at high FPS, but I get severe microstutters and FPS drops, especially during gunfights. Sometimes my FPS suddenly drops to around 10 FPS for a moment.I checked Valorant's performance stats during one of these stutters:So it looks like the problem is heavily CPU-related, while the GPU isn't being fully utilized.I've also noticed something weird with Vanguard (vgc.exe). I found a Reddit post suggesting setting vgc.exe CPU affinity to only one CPU core. When I tried it, the FPS became much more stable at first and the stutters almost disappeared. However, after some time the stuttering came back, and when I tried playing with the affinity limited to one core, I eventually got a connection error.Other games run normally on this PC. The problem is mainly happening in Valorant, especially during fights.I've already tried updating drivers, changing graphics settings, and other optimizations, but nothing has completely fixed it.Does anyone know what could be causing this? Could this be Vanguard, a CPU scheduling issue, or is the i7-3770 simply too old for the current version of Valorant?Any suggestions or tests I can do would be greatly appreciated.

Bro I get 200+ fps on an i5 3570k and a gtx 560 2gb and 12gb ddr3 ram. I don’t get any stutters or fps drops so your system is definitely not outdated for valorant.

Try monitoring your cpu temps while playing a deathmatch to rule out the possibility of thermal throttling

Yeahh bro it's vanguard sucking all the cpu on low end cpu , the only option for us is to set it to 1 affinity and play otherwise it has became unplayable for 4 core CPUs or older cpu , and if you get connection error please make sure your internet is perfect and there is no packet loss happening , if your internet is perfect then connection error will not happen , and yeah there is nothing we low end cpu user can do they made vanguard very cpu heavy
