Gamma correction . To adjust the brightness of colors in textures.

Window captions . Whether or not you want colorful caption-bars. Just for presentation.

Activate windows on . Whether or not you want to have windows auto-activated, when the mouse- pointer is inside them.

If not selected  and If selected . Affects with what color, blue or brown, icons that are selected, should be shown with.

Select 3D viewer . If you have a 3Dfx-compatible 3D-acceleration graphicscard installed, QuArK will use it to speed up drawing in 3D-windows. If you don't have one, you must select Software-only.

Entities in 3D . Whether or not QuArK should draw entities (3D-models) in the 3D-windows.

"Far" distance . How deep QuArK should draw in the 3D-windows. Lower values will speed up drawing.

Vertical view angle . The field of view of the perspective views, in degrees. Just as with cameras expected it is not the width but the height of the view that you enter.

Frame color . The color to use on the bounding area of the 3D-windows, where QuArK won't draw due to the choosen size of the view.

3Dfx card owners only

Second monitor on 3Dfx . If you have two monitors, one connected to your regular 2D-graphicscard and one connected to the 3Dfx-acceleratorcard.

Full-screen gamma correction . As it says.

Full-screen size . As it says. Do not go above what your 3Dfx-acceleratorcard can handle. A typical max value would be 640 480.

Fog density . The lower the fog, the more you can see, but keep in mind that the "Far" distance and the fog density are somewhat connected.

Fog color . Want green fog? Change it here!

Isometric transparent fraction . Ehhh, read the flyover-help yourself, and experiment with the value if you want.

Software drivers only

If you have selected 'Software-only' in the 3D-viewer, then you can here change how fast the software-render should be able to draw things in the 3D-window, while standing still and while walking/moving around.

Mouse sensitivity

All these values controls the mouse sensitivity, when you use your mouse to move around in the 3D-windows.

Keyboard settings

Instead of using the mouse to move around with (which can be quite difficult at times), you can either use these standard movement-keys when the 3D-window is active, or redefine them to suit your needs. It is highly recommended that you know how to move around in 3D-window using the keys.

Keyboard movement dynamics

Change these values if you feel, that moving around using the keys, isn't quite fast or slow enough. You must experiment a bit to find a setting that you like using.

Settings in this folder are only usable if you have a true OpenGL graphics-card.

3D-accelerators like 3Dfx, Voodoo, Voodoo-II and other low-price cards, are not true OpenGL compatible, they only emulates it through a Glide-driver.

Values in this settings-folder, controls how much memory QuArK are allowed to consume, and the number of undo-levels that it should store.

Controls syntax-highlighting in QuakeC source-code.

In this folder, you are able to setup which file-extensions should start QuArK, when you double-click on a file in Windows File-Explorer.

Some of the file-extensions in this folder, QuArK might not be able to edit yet, but you can always import them into your QuArK-project, and send it to an 'external editor'.

You can select there your preferred program for editing various file types that itself QuArK won't let you edit.

Each box can be empty (no program), or <open> to call Windows' default programs for this file type, or a complete program path to call a specific program. Other commands in square quotes like <edit> may be available depending on the program.

If a box is left empty but QuArK knows how to convert to another data type, the conversions are done automatically (e.g. if you leave the .wal box empty but fill the .bmp box, when you want to edit a Quake 2 texture (.wal), QuArK will convert it to .bmp, call your program, and convert it back to .wal after you edited the image).
