Why is dead space controls laggy

Yet his PC ran the game pretty well, with very little difference between aim-mode and regular mouse sensitivity. This discovery launched another round of troubleshooting. I came home and fired up my second test rig, with a Radeon HD X2 and a Core i Extreme, to see if using a different video card was somehow the key to the control problems.

At first, the Radeon-based system seemed to be a night-and-day improvement. Controls were fluid and responsive with only vsync disabled, even without forcing on triple-buffering. However, as I played through the game, I realized that the responsiveness of the controls and the disconnect between aim-mode and regular controls both seemed to vary depending on the situation.

Enter a large room and scan for baddies, and control seems great. Walk into a small bathroom on the ship or turn and face a corner, and the controls would slow considerably. Slowly but surely, a little light bulb icon pulsed to life above my head. Could it be that the problem was worse when the video card was doing less work, when it was rendering the game too quickly? Right away, I noticed that frame rates in the problem areas were approaching frames per second, while open areas with smoother controls ran closer to FPS or less.

Solving the problem with the GTX s was tough, however. Let me explain what I mean by that. Even when using my older, lower-DPI mouse, the sensitivity and responsiveness were excellent. I could turn my character around with the flick of a wrist when needed. The mouse sensitivity in aim mode may have been a little bit slower, but not by much. And yes, I was more likely than most to encounter this problem in a really nasty way, given the sort of hardware I was packing.

The easiest workaround is to make sure you use sufficiently demanding graphical settings to keep frame rates from getting too high. However, this fix is only partial, because frame rates will vary as you play the game. Another avenue for addressing this problem, strangely enough, is to enable vsync in the game itself. And controls are very consistent with this vsync frame-rate cap in place. The obvious drawback here is the locked 30 FPS refresh rate, which looks slow and not especially smooth to my eye.

Your PC might just be too fast for its own good. Update: Voila! As a couple of commenters have noted, enabling vsync in the Nvidia drivers appears to lock frame rates at 60 FPS, which is pretty much a best-of-all-worlds fix.

The menus and the game controls both work nicely. Even SLI works perfectly. Apparently, you end up with that 30 FPS cap, sluggishness, and imprecise mouse control in menus if you have vsync set to follow the application setting in the drivers or perhaps forced off and then have vsync enabled in the game.

The fact that the game released in the state it did is just sad. I have a theory this might have something to do with mouse acceleration. That is, the mouse becomes more sensitive when you consistently move it in one direction to allow you to turn quickly when you really need to. And less sensitive when you change directions or move inconsistently as when trying to zero in on a target. The acceleration algorithm may be based on the change in mouse position from frame to frame and works best on some 60 fps.

Any faster, and the updates in the mouse position may happen slower than the rendered frames, thus producing an inconsistent movement and a loss in the acceleration effect or even lurching and wobbling. My USB mouse has a 10ms packet sending interval, which means a maximum of updates a second.

Comparatively its crazy slow to what we have out today. With the Xbox though i would say it has to be something else other than the clock speed of the cpu or some other part, as the game dynamically gets crappier as the frame rate increases.

So the clock speed is a near perfect match. Unless i am just not thinking clearly at the moment and massively missing something. Keep me logged in on this device Forgot your username or password? Don't have an account? Sign up for free! What do you need help on? Cancel X.

Set your resolution to the highest possible. Turn Vsync off in-game. If you want vsync on, force it from your control panel. User Info: GodlyRanger.

Vsync is totally broken in DS1. It works fine is DS2, but hooooly goodness is it awful in DS1. I couldn't even believe I was playing the same game after I disabled it! That's not entirely correct. This problem is also present on computers which are above the system requirements. I have an Core2Duo with 2.

Bobby, same here. Modern rigs will have trouble until you turn that off. I can confirm that v-sync is terrible in Dead Space 1. Turn it off and use a different program e. If you have a powerful modern PC, you'll most likely need to turn v-sync on in some way if you intend to keep playing after getting the Plasma Cutter. EncoderX EncoderX 51 1 1 bronze badge.
