For some context, I have a pretty beefy rig. 3900X, 2080S, 32 GB 3200 MHz RAM, NVMe SSD, G-Sync 144 Hz panel (1440p, 1 ms latency). My drivers and windows are also consistently kept up to date with default settings used (generally speaking). But, I notice in many many PC ports that I've played microstutter/hitching/stuttering is common as day. But why? In my opinion, microstutter/hitching/stuttering is the single greatest evil in gaming -- input lag is probably the second great evil, but for me microstutter is just a nightmare that ruins my fun and it's just really jarring. In general, I see this most in open world games (Assassin's Creed Odyssey, Far Cry 5, Batman Arkham Knight, Outer Worlds), but it does also happen in other sorts of games (Battlefield V in DX12 mode is a stuttering mess of a game in my experience and even the more recent Control on its latest patch stutters occasionally). "Cap FPS" you might say -- oh, boy I do (I try in-engine/RTSS/new Nvidia limiter) -- I certainly try, but it often doesn't solve the problem. For example, Master Chief Collection (Halo Reach) if you cap to any value other than 60 with the in-engine limiter, the game stutters like crazy. RTSS doesn't work here. In Assassin's Creed Odyssey if you cap to any value with RTSS even with zero dips below your target on the frametime graph the game stutters seemingly at random in my tests. The in-engine limiter does the same thing. Battlefield V when capping FPS in DX12 mode has the rare, but present microstutter when capped with RTSS -- despite no dips on the frametime graph. Witcher 3 is also still a stuttery mess barring an aggressive fps cap in my experience to boot too (Novigrad thrashes the tar out of CPU and seems to microstutter noticeably quite a bit). Dark Souls 3 seems to stutter every now and then seemingly at random and even capping to 30 fps via RTSS did not solve this for me. Meanwhile we occasionally get GOOD PC ports like DOOM 2016 and DOOM Eternal which never ever stuttered once for me outside of checkpoints. Also, Hunt Showdown from Crytek is quite smooth in my experience as well for example so it's clearly possible (EDIT: eh, could be a driver issue or something, but this game does have a slight “jitter” with uncapped FPS for me even with Gsync — with capped FPS the game looks noticeably smoother now). Red Dead Redemption 2 and GTAV barely stutter for me ever if at all too so clearly it can be done with open world games. Anyway, all that to say, why can't devs seem to get this right? Why is it that so so so many PC ports stutter like crazy/have microstuttering as a problem? Meanwhile on console, those versions simply do not display this problem in my own tests at least. I've tested these games on three different PCs for what it's worth (my last desktop/my laptop/my new desktop) and the issue is always there for these example games.
