One big issue that I face is the delay between shooting a bullet and the kill actually registering. Some games I’ll be able to instantly kill someone as soon as I fire a bullet with no delay. Then the next game I’ll fire a bullet, hit the guy in the head but he won’t die for a fraction of a second. This happens more often with Chamber’s deagle which idk if that helps. I have consistent 15 ping, consistent 200 FPS (Capped fps), and no packet loss. I can instantly tell if the game feels “sluggish” by how fast my kills are being registered after I shoot a bullet.
Hey - the sluggish feel that you described is one of the issues that we're testing a fix for: network buffering adding excessive round trip delay in a few situations. Alt-tabbing, high network jitter, or client hitches can all cause buffer durations to spike up temporarily. In the cases we've seen, this resolves itself after a short time, but it can be pretty noticeable if you take a fight during that window. If you alt-tab frequently, turning off background framerate throttling may help reduce the impact until fixes go live.
In addition to fixes, we'll also be adding a graph that shows the full round trip latency (including buffering on either side), which should give you some hard evidence if you run into this sort of issue. If you're still having trouble after the changes go live, check that graph and let us know what you're seeing.
