The Massassi Temple: Jedi Knight Tweak Guide

This guide is basically to compile a bunch of useful "stuff" for newbies and/or people who just haven't gotten very deep into the game. This guide is designed to help you get the best performance/image quality out of your computer. It should also help you out with some basic tuning tips for the actual gameplay. It is separated into the following parts.

This guide should not be taken as pure fact, it is just a compilation of observations by someone who has been playing JK for a long time.


This section is divided into 3 parts.


Framerate is generally measured in "frames per second." It is the number of frames of animation your computer is displaying at any given time in JK. There are no benchmark utilities or time demos for JK, so you just have to estimate averages when you are trying to test your framerate. Think of JK as a cartoon, made up of tons of different still pictures, all played in sequence to form an animation. The more frames of animation your computer displays, the smoother the movement will be. Signs of bad framerate are choppy animation, a slide show effect, general slowdown and/or enemies/players jumping around the screen (which can also be LAG, or latency).

Framerate has a direct impact on the gameplay. If you are in a multiplayer game, and you have a framerate of 15, and your enemy has a framerate of 60, they will have a very strong advantage! First, their aiming will be a lot more accurate (no slide-showing past and having to compensate for each aim). Second, they can run circles around you while your computer tries to keep up. Third, if your computer is trying so hard to keep up with the framerate, it's very likely that it is also having problems keeping up with the network side of things, so your computer could be dropping packets.

There has been huge argument over how fast the human eye actually sees. Movies run at about 24 frames per second. In theory, that means that if you have 24fps in JK, you will be doing pretty well. However, this doesn't take into account the fact that movie screens (and real life) are refreshed all at once, while monitors are actually refreshed vertically (which is why computer screens on older movies always flash). I generally like to keep my framerate over 35. This ensures that even when a battle is going on (IE: a more complex scene) your computer will be able to keep it up. Remember, framerate is always changing depending on what is being rendered - the more complex a scene, the more power it takes to keep everything up and running smoothly. If you want to read more on this framerate debate (30 vs 60 frames per second), take a look at this article.

To actually display your framerate, start a game up, then type t to get to the console (or in multiplayer, type t then Tab). After that, just type framerate. This will put a number at the top of your screen (that should change as you walk around). This is your framerate in frames per second. 30 is decent, but higher is better. Go fight some battles and see what happens. You don't want this to drop below 30 - battles will often do that. What's the point of turning up the resolution (discussed below) so you get a nice 30fps when you're walking around, but then it drops to below 15 during a battle, when you need it most!?


Resolution is basically how many pixels are displayed on your screen at once. A good general discussion on resolution can be found here. Basically, the higher your resolution, the better the game looks. On the flip side, the higher the resolution, the more computing power it takes.

To get to the display settings, just start up JK, choose your player, choose setup, then display. You will see a box listing all available resolutions with your monitor/video card combo. Generally, if you have a Pentium 1 based computer, you should try 640x480. Most P2's can handle 800x600 easily, and even 1024x768. It gets difficult to read messages if you go any higher than that, but it looks better, so if your computer can handle it and you don't mind missing the messages, feel free. If you are on a Pentium 1 in software mode (IE: no 3d card, which is explained below), you may want to crank the resolution down even farther. I used to play at 320x200 just so I had a decent framerate. Sure, it looked bad, but the gameplay is where it's at!

3d Acceleration

3d Acceleration is when JK uses the 3d features of a 3d card that's installed in your computer. In order to use JK's 3d acceleration features, you must have a supported 3d card installed. Basically, a 3d card takes a lot of the geometry processing load OFF the CPU, thus freeing it up for other things (transform and lighting, floating point operations, ai, 2d processing, etc). The 3d card also smoothes out textures so they don't look so pixelated, reduces the "jagginess" of polygon edges, and supports advanced features such as multiple transparencies (in some cases), better lighting effects, etc. 3d acceleration often allows you to turn the resolution of the game way up. This is because it takes a huge burden off the CPU, freeing it up to crunch more numbers and feed polygons to the 3d card.

Most computers nowadays (if not all) come with some type of 3d Accelerater Card installed. This card can be a separate 3d card, or it could be built in to your 2d card. Either way, JK supports most 3d cards. However, even if you have a 3d card installed, you must tell JK that you want to use it! If you don't, you will not be taking advantage of the 3d acceleration features of your card and the game. To turn on 3d acceleration, just start the game, go into setup, click display, then check the "Enable 3d Acceleration" box. If the box doesn't appear (it should be above the resolution list), your card most likely isn't supported. Once you check the box, the resolutions will change to all valid 3d accelerated resolutions. Higher looks better, as discussed before, but make sure you keep a good framerate. Just to show yourself the texture smoothing and image quality enhancements of your card, try 640x480 in software, walk around, test the framerate, then go back, check the box, and walk around some more. There should be a very noticeable difference.

Another thing that most 3d cards support is colored lighting. JK itself doesn't have colored lighting, but it's addon pack, Mysteries of the Sith, does. You may have to check the "enable colored lighting" box in the display options to see it. Colored lighting really makes the game and the engine look a lot nicer.

On a last note, some computers (especially ones that use 3dfx Voodoo series cards) have a separate 3d card. For instance, someone may have a RivaTNT card as their primary 2d card, which also has a 3d core. Attached to this could be a Voodoo 2 3d accelerator card. People do this often in order to play games that only support 3dfx glide based 3d acceleration. By enabling JK's advanced display configuration menu, you can choose which 3d core (in this example, the Riva or the Voodoo) JK uses. You can only use one at a time. In order to enable the advanced menu, you will have to run JK from the command line. Click Start, then Run then the following:

C:\Program Files\Lucasarts\Jedi Knight\jk.exe -displayconfig

This is assuming that JK is installed in the default directory. If not, you will have to type in your directory structure. For example, if JK was installed in C:\Jedi, you would type: C:\Jedi\jk.exe -displayconfig. Remember, Windows/DOS is not case sensitive, so C:\JeDi is the same as C:\JEDI and c:\jedi.

Once you have started JK, just go to the display menu once again, and towards the bottom, there will be an "Advanced Options" button. Once you go in there, there are all kinds of options, but the only one that will help you is the box that allows you to choose which 3d card you use. Primary Display Driver will be your main 2d card, or your main 2d/3d card, whichever you have. Under that, if you have a separate 3d accelerator, you will see it listed. Just click on it, press OK, and JK will use that one from now on (unless you go back and uncheck then recheck the 3d box - if that's the case, you will have to reset the display as outlined above). The advanced options tab will only show up if you start JK with the -displayconfig switch.


This section won't be as long as the previous, but the stuff is equally important for a good playing experience. First of all, throw away your joysticks and break out your mouse. That's right! Most First Person Shooters are best played with a mouse. The mouse allows you to easily and accurately aim. The mouse also allows you to easily navigate around - you can do a full 180° turn with the flick of your wrist.

The mouse can be a little difficult to get used to, but once you do, you will never switch back. Generally, people use the left mouse button for fire, and the right for jump. Another popular configuration is Fire1/Fire2 for JK (since it has multiple fire modes for most of the weapons).

So, your right hand is on the mouse, and your left is on the keyboard (unless you're left-handed, in which case this will probably be reversed). Your keyboard hand should not have a "turn right" or "turn left" key. Those are just a waste. You should use your mouse to navigate. A better setup is to have a "strafe left" and "strafe right" key set. This allows you to slide left and right, dodging projectiles, while still keeping your sights on the enemy.

This setup also allows you to "circle strafe," which is a method of circling your opponent while keeping your sights steady on them. You just strafe one way and move your mouse sideways the opposite way. Once you get used to this, you will be able to literally run circles around a lot of players.

The rest of the controls aren't critical. A lot of people bind their most used force powers near there, as well as "activate" - make sure you have enough keys to use as you need to (the number pad is a good place for your left hand).

Other controller related tweaks that are important include:


JK supports 3d positional audio through A3d, a 3d sound standard. Any A3d 1.0 card should support this, as well as most other 3d sound cards nowadays (through a wrapper). All you have to do is go into the sound setup and check the "enable A3d sound" box. This box won't appear if you don't have a supported sound card.
