This is because with an uncapped framerate, your game could be easily running at a few hundred frames per second (it's a pretty old game now!), which this port is just not used to dealing with. Okay, so that fixes the mouse lag, but (usually) replaces it with a few new problems terribly low mouse sensitivity and a well-known gamebreaking bug that can stop you progressing near the start of the game. It's easy enough to switch off, just go to the visual settings like so: This is the cause of the horrible mouse lag / acceleration, making it pretty unplayable.

Funnily enough, whoever ported the game thought it would be a good idea to not only turn v-sync on by default, but to cap it at 30 fps (which isn't v-syncing really. Forcing v-sync and triple buffering through the Catalyst Control Centerīut have been met with little success, then this guide is for you.ĭead Space dearly wants to run at your monitors native refresh rate (typically 60 fps or hertz). If you have an AMD card and have tried such fixes as: A guide for that can be found here ĮDIT 3: Thanks to CaptnFantastic for advice and further testing on alternative methods to use in RadeonProĮDIT 3: Thanks to gr8sho for finding a solution for users playing the game with OriginĪfter trying to get this game to run properly using existing suggestions from the steam community discussions board, I finally stumbled upon a solution that worked perfectly for me. I have since updated the guide (specifically step 2) with different settings that eliminates the screen tearingĮDIT 2: While is guide is for AMD users only, Nvidia users can use a similar program. This fixed most of the issues but also resulted in some noticeable screen tearing. If this guide ends up helping you, then please rate it up!ĮDIT 1: I originally posted this guide suggesting to use the Lock frame rate to monitor's refresh rate option in RadeonPro. Please do give feedback in the comments if you are still having issues or suggestions. If you've tried some of the other fixes, but the game still doesn't work quite right, then this guide might be for you. This guide is quite simple, however it uses a 3rd party program called RadeonPro and therefore is for AMD card users only. After finally finding a solution that made the game run flawlessly, I decided I should share it with others. I spent a long time trying to find a sure fix that would let me play the game as it was intended.

The port for Dead Space 1 isn't perfect, and nigh unplayable on some machines. Framerate slowdown? Mouse acceleration and sensitivity issues? The invisible door bug?
