Slight stutter periodically (Vsync issue?)

[Nicholas Steel]

The PC version of the game is exhibiting a strange momentary stutter every so often that does not appear to be a frame rate issue. Any ideas on how to resolve this?

The Xbox360 version works great on my TV (not the same display) excluding the other problems that plague it (Poor performance over time in a single session for instance)

Samsung P2350 monitor
1920x1080 fullscreen, disabling vsync introduces terrible screen tear and as such is not a solution. Vsync is always enabled.

Intel i7 920 @2.66GHZ
ASUS P6T Motherboard
Nvidia Geforce 560Ti 2048MB (314.22 drivers)

bumping this. it sounds like I have the same problem.

but in my case, it is framerate-related. fez ocassionally speeds up for me and goes above 60 fps, and when it does this (it usually races up to 67-68 fps, jumps around these numbers a bit, then falls back to 60), I get very noticeable stutter and some screen tearing, ocassionally, I even get minor graphic glitches (some black rectangles popping in for a frame or two, mostly in the upper half of screen).

1920x1080, fullscreen
win7, 64 bit, i7 920, asus p6t, hd 7850 O:

seeing how I and OP have the same mobo and cpu makes me think we might be special, hah. let's hope this ain't so.

bump. seriously, no one else?

I get the glitchy screen too, may try the 60HZ fix before starting the game to see if that helps

[[D.P.N] wolf_squad]

I've tried the command line 60 hz fix, I've tried forcing the vsync externally via d3doverrider. nope, somehow none of this works. while not a major bug, it does ruin the experience.

It still happens, though the recent update may have slightly improved it (Might be just placebo effect though)

[[D.P.N] wolf_squad]

it did completely nothing for me. I've discovered that filming what's happening with fraps (I was trying to catch 'em glitches on film) completely solves the issue, and game is buttery smooth 60 fps. Argh.

[Nicholas Steel]

Yeah xD. Better off running a camera on a tripod or a HDD Recorder or some such to capture your monitor's output.

Also happening in the linux version. Probably just a problem with the game itself

[REDGrim]

I have the same thing happening on my monitor. It's a Compaq FS7600 (Pretty old monitor) 1024 x 768 Resolution, though it recommends 1280 x 720 and there is no setting for my resolution.

Well, putting it into windowed mode seems to fix the issue, however...while the screen tearing is gone...eck...I can't deal with games that aren't full screen...and the bottom part of the game window doesn't show since it's behind the bar thingy.

[[D.P.N] wolf_squad]

yeah, windowed mode is forced into 60 hz properly, so no stutter happens. if fez added borderless windowed mode, that would be a practically perfect solution.

So long as it retains its own Vsync implementation that would be fine, as I'd disable the DWM/Aero to prevent that ♥♥♥♥♥♥♥ around with vsync causing needless stutter and if the game lacks its own Vsync implementation then you'd obviously get screen tear.

it's locked to 60 fps internally. trouble is, it uses opengl, and only windowed mode forces 60 hz vsync properly with amd cards in this title. d3doverriders and the like don't work, since this is, well, not a d3d title. but forcing vsync in opengl game for amd cards seems to be quite troublesome. I really doubt dmw/aero on modern computers can cause any trouble at all.

You'd like to think the dwm/aero isn't problematic and I may be the exception, but here it causes excessive stutter for all software except those that operate in a fullscreen exclusive display mode. I've never been able to figure out why and it has been like this ever since Windows 7 was released. Out of all the programs that don't use a fullscreen exclusive display mode, Adobe Flash Player has to be the most annoying.

Disabling Aero (Switching to Aero basic or disabling the DWM service) resolves the problem completely, but then I'm at the mercy of the programs/games featuring their own method of Vsync and some programs simply lack such functionality and forcing it via the display drivers doesn't achieve anything for those programs. Also I experience excessive screen tear in most programs when Vsync is disabled.

getting artifacting, which may be related to this issue. this wasn't the case when i first bought it, i think new AMD drivers or something? Now there's like a flickering black bar across the screen most of the time, like the display is cut in half
