Cmon you guys are holding out. Give me some gamez!!
There are literally hundreds / thousands of games that run smoothly from Doom to Deus Ex to Dragon Age Origins to Dishonored to Don't Starve, etc. You need to spell out exactly what games / genre's you like to give people a chance at coming up with something relevant. Old or new? Just FPS or other genres? Are old games which originally stuttered on old hardware at time of launch but run fine now due to patches / better hardware acceptable? Are you talking about only performance related stutter, or are you including non-performance related stutter specific to certain engines? Stutter on both GPU brands or just one? Stutter in general or your system in particular?
As people have said, stutter and optimization are not interchangeable. Some recent engines stutter occasionally no matter what due to the way lazy devs code predominantly for the consoles, and then leave console defaults in the PC port that "streams" data as if it were a last-gen console reading directly off an optical disc. I've found modern Unreal Engine 3/4 games to sporadically stutter no matter what whereas earlier UE1 (Deus Ex) and UE2 (Bioshock 1-2) games were silky smooth even on much slower hardware. Same goes with the Unity engine, even low budget Indie first-person horror games will often run horribly due to using the awful Unity defaults left in. That side of things is down to optimization. But other stutter / micro-stutter is often I/O related, ie, a game may stutter on a 5,400rpm HDD more than it does an SSD, or Crossfire / SLI issues. Or you've got something running in the background. Or it's simply "that kind of game" like Oblivion / Skyrim where you'll never really get 100% flawless 60fps min performance due to the nature of such open-world games that divide the world into invisible cells then "stream in" a large amount of data all at once when loading new cells as you travel across the map. Some games stutter badly with in-game VSync, but disabling that and forcing GFX driver VSync otherwise works fine.
Random stutter is often highly system specific. Eg, my secondary rig is a HTPC / light gaming rig. It used to have a 7790 GFX card in that stuttered like crazy during the first 5 seconds of game on every single UE3 game (Bioshock Infinite, Dishonored, etc). Since then, the card has been side-graded to a 750Ti (barely +10% faster) and now all that stutter has disappeared. The stutter wasn't "
performance on a low-end card" issue as I initially believed, it was down to default game engine settings differeing for AMD vs nVidia. And such engines can often be tweaked via config settings files.
Eg for UE3 engine games ini file settings:-
bUseBackgroundLevelStreaming=True
DisableATITextureFilterOptimizationChecks=True/False
UseMinimalNVIDIADriverShaderOptimization=True/False
For Deus Ex Human Revolution:-
In the registry, locate "AllowJobStealing" and change to 0
For NVIDIA owners : locate "\Graphics\AtiForceFetch4" and change to 0
Skyrim:-
There are far too many ini tweaks to list (bUseThreaded*, decals, shadows, shadowmapresolution, x LOD / view distance, etc), but the key is use common sense. By all means install some graphical mods, but don't cram everything in there then complain about stutter. Eg, on low VRAM cards use 2K instead of 4K HD texture packs. Install
one decent weather & lighting combo rather than half a dozen conflicting ones (personally, I use ELFX + PureWeather but no ENB's). I also use injected SMAA instead of in game MSAA / FXAA. End result = people have been impressed at how well it runs on a 750Ti (near constant 60fps), whereas some GTX 970's are plagued with sub 40fps stutter purely from the owner getting so carried away with extreme modding that the engine ends up over-saturated.
Playing around with stuff like the above can significantly reduce stutter. And you get to play some great games instead of writing them off on the back of unrealistic expectations of "
infallibly perfect 60fps min during every second of game-time". Someone said earlier that Age of Mythology stuttered. I've had that game since it came out (and still have the 2002 retail discs) and haven't seen any such stutter that wasn't related to stuffing in too many units on a slow CPU (the game is single-threaded). You said Bioshock Infinite is still broken. Mine isn't. Early game stuttered like crazy at specific "stream in" invisible checkpoints on the map. One patch improved it, but the later patch has actually eliminated most of it. Now the game runs better on an i3 post-patch than it did on an i7 pre-patch.
Other examples : If you play with VSync on, then Triple Buffering may make the difference between 60fps to 58fps slowdown = either a 2fps drop (TB on) or a 30fps drop (TB off), etc. D3DOverrider may fix some such problems with games not supporting Triple Buffering. Some people close their web browsers (or at least flash heavy tabs before gaming), others don't. Some GFX card + driver combos can mess with short "glitching" of lowering GPU clock frequencies to idle whilst gaming (one of several reasons why reason I ditched the 7790 for a 750Ti), many others don't. Your choice of 4-8x MSAA anti-aliasing may hit a VRAM limit before someone else's choice of FXAA / SMAA (may use up to 200-300MB VRAM less which gives them 10-15% more overhead on a 2GB card), etc. So many different variables like that can mean that a game that stutters for you on your system may not stutter for someone else on theirs.
