Make sure you're measuring loaded ping jitter.
When somebody else in the same house does a Netflix, it will jitter your gameplay packets around, giving you teleport effects. If you want to minimize teleporting, buy a 2nd Internet connection that's just dedicated to your gaming PC, or find a way to use aggressive QoS prioritization with an Ethernet connection to a super high performance 4-core or 6-core multigigahert-CPU gaming router. Remember that even a 10ms packet jitter might, for example produce a 10 inch teleporting effect during movement of 1000 inches per second. And jitter can be worse than that, especially in momentary latency surges on a cheap router on a heavily loaded ISP at peak period. Like a 100ms jitter once every few seconds -- nasty teleport effects can occur from that in some games. It can also be the server's fault (try a different server), a traceroute fault (try a gaming VPN to force a different route to same server), or local congestion (node congestion, inhouse congestion, etc).
Try temporarily testing a different link (LTE, Cable, DSL, FTTH, etc). Sometimes some people got better effects from LTE than FTTH, in weird unexpected situations, but it's usually FTTH that reigns supreme in low jitter...
If you absolutely must esports on WiFi, make sure you're on 11ac or preferably 11ax, very close to router. Maybe get a 2nd dedicated router (like Quest 2 users often do for VR streaming, even from the same ISP in the same house). 11n will be very ugly teleport effects in Valorant.
Also, as a test, temporarily decouple framerate by uncapping it, and use VSYNC OFF at framerates above Hz (see
advantages of frame rates above Hz). There will be ugly tearing, but microstuttering might go down, since the network packets may be interacting badly with a hard-capped low VRR frame rate (like 72Hz). If microstuttering weirdly disappears with VSYNC OFF, then buy a higher Hz monitor to eliminate the tearing/microstutter problem for very specific games whose network logic interacts badly with framerate caps.
There are a ton of factors why microstutters shows in some games and not others. Sometimes easily fixable, sometimes harder to fix.
