For the Steam PC release, titled Dementium II HD, start with the game’s main-menu Options: adjust its available video settings and remap controls to suit your setup. The PC guide lists a maximum selectable resolution of 1920×1080 and defaults for both keyboard/mouse and controller. Steam publishes minimum and recommended PC specifications, but neither source provides frame-rate benchmarks or a verified optimization fix, so treat any performance change as something to test on your own system.
Start with the documented settings
- Open Options from the main menu. The PC Quick Start Guide places control customization and video settings there.
- Review the available video options. The guide confirms video settings can be adjusted and resolution can be selected up to 1920×1080. It does not specify a graphics-quality slider, individual effects, or a target frame rate.
- Change one setting at a time, then check how the game feels. The available sources do not establish that a particular setting improves performance. Treat changes as experiments, not guaranteed fixes, and note what you changed so you can revert it if needed.
The ceiling of 1920×1080 is a supported resolution, not a performance recommendation. The sources do not say which resolution will run best on a given PC.

Use the list as a basic compatibility check: compare your operating system, processor, memory, graphics hardware, and DirectX capability with the published entries. Meeting the recommended specification does not establish what frame rate to expect, because Steam provides no benchmark results or performance target.
#1 Best Overall
- With broad game support, the Logitech Gamepad F310 works with old standbys to today's biggest titles, so it's easy to set up and use with your favorite games.
- Profiler software allows the gamepad to be programmed to perform keyboard and mouse commands for games without gamepad support.* * Requires software installation.
- A familiar control layout that doesn't require a learning curve to be able to use, with all the same buttons as on an Xbox 360.
- The unique floating D-pad rests on four switches-instead of a single pivot point-making it responsive to quick changes in direction.
- The six-foot cord lets you lean back and play a comfortable distance from your PC monitor.
Steam’s listing also notes that the Steam client supports Windows 10 and later beginning January 1, 2024. That is a client-support notice; it does not replace or update the game’s separately displayed operating-system requirements.

Keyboard and mouse
This layout uses WASD for movement and the mouse for looking, with the left mouse button for firing. It may suit players who prefer mouse aiming or already know this style of control. The sources do not establish that it is faster or more accurate than a controller.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsController
The guide assigns movement and looking to the two analog sticks and lists buttons for the other actions. Choose it if you prefer that layout and have a controller available. The sources do not guarantee compatibility with every third-party controller.

What to try if performance still feels poor
The cited documentation does not provide controlled frame-rate results or validate driver updates, compatibility settings, display-mode changes, or other system tweaks as fixes for this game. If you try such changes, make them individually and regard the result as specific to your PC rather than a documented universal solution. The source-backed starting points are the in-game video options and the published hardware requirements.
