The first stable release of JkGfxMod is now available for download.


JkGfxMod


What is JkGfxMod?

Getting Jedi Knight: Dark Forces II (JK) and its expansion pack Mysteries of the Sith (MotS) to run properly on modern-day computers is notably fiddly and previous methods for getting the game to run have largely ceased working - and in many regards carried issues of their own.

While fully functional engine remakes for JK have been worked on since the early 2000s, for the moment JkGfxMod's aim is to be the most hassle-free way to play the original games on modern computers.

Before:

After (with all enhancements):

Graphical enhancements

Furthermore, JkGfxMod has been designed to enable various graphical enhancements to bring the game a bit closer to more contemporary game graphics.

Starting point:

JkGfxMod 1.0 - JK JkGfxMod 1.0 - MotS


1) The Neural Upscale texture pack (MotS) enhances the original textures of the game, so that the look of the game stays true to the original:

JkGfxMod 1.0 - JK JkGfxMod 1.0


2) It's possible to retain the original graphics with more up-to-date lightsabers and weapon effects (MotS):

JkGfxMod 1.0 - JK JkGfxMod 1.0


3) Or you can go fully out with the currently available hi-res graphical update packs for the game (in MotS as well):

JkGfxMod 1.0 - JK JkGfxMod 1.0 - MotS


With time, patience, interest, patience, skills and patience at hand, you can go beyond the normal game itself and brush up old mods as well:

With the first stable release of JkGfxMod, you should now be able to keep previously present graphical stuttering and lag issues at bay with the texture preload setting in the jkgm.json file. Even though this will increase the pre-play loading times (after running the EXE but before the game itself starts), it should hopefully be worth it in the game itself. Take a look at my jkgm.json file as an example, if necessary.


What's next?

While these are major improvements in getting JK to work on modern systems, new problems will still arise and sadly some of them ultimately can't be addressed by JkGfxMod. Keep an eye out for possible updates on GitHub, and report any new issues there as well.

All that said, JK still remains as fiddly as ever, and you might need to work on additional mods to make the age of the game stick out a bit less.

Enhancement Mod for JkGfxMod (MotS version)

And don't forget the following:

* JkGfxMod (namely inject.exe) often results in a false positive reading by virus scanners. While downloading JkGfxMod from ModDB or GitHub should be perfectly fine, remember that the source code for JkGfxMod can be viewed on GitHub and can be compiled on your own if you can't trust the downloads

* Start a new game: Save files in JK and MotS cannot be reused after installing or removing most mods.

* If you properly install an optional material pack and the textures are not showing up, try setting the brightness slider all the way to min. The brightness slider can be found in Setup → Display → Brightness.

* JkGfxMod streams materials from storage as they are needed. This may cause some stuttering, especially if JkGfxMod materials are installed on a slow hard disk. This can be corrected by adding a vram_texture_preload_size entry to the configuration file.

For further information, check out the JkGfxMod documentation:

Are there any plans to do this to MotS? The textures are painful to look at, even with the gfx mod on that one.

You can use this for MOTS. the game has the same textures as Jedi knight and then you can get the projectiles upgraded here:

Can I load JKE and JKR textures over most of these? I prefer the JKE-R ones

Not sure what will happen if you try to run both but you can try just put JKR.gob into your Resource folder in your Jedi Knight directory and run the inject as admin. If that doesnt work you can always go into the texture folder in Materials folder and detete the textures you dont like etc..

Stay away from it if you want to use it with Steam Overlay or Steam.

Shame I don't get to use this. I use a Steam copy, so either I rename the Steam exe to 'JK' in which case it won't open, or I keep it as JediKnight which makes the JKGFX mod (and by extension this) not load.

There is that video guide above but his game magically loads where mine does not. Likely due to a Steam hotfix at some point since.

Don't really care enough for the game to re-buy it.

Anyway, I still commend you on the work, it looks really good in screenshots. Probably pretty nice for anyone with disc copies.

Finally got-it to work. Follow his steam instructions, but use jkgfx 0.0.10 on git hub, rename jk.exe to jediknight.exe, turn AV suites OFF, run inject as admin and then, the game will load (don't forget to edit the weird .jsom file and put the resolution to what you will use, don't put windowed mode, maybe upscale the hud). Go in settings in the game menu, enable acceleration, choose your resolution, put luminosity to minimum and start A NEW GAME! Worked for me when I tried again, 1st time around, had the same trouble as you.

I'm on a clean install and I'm using the latest JkGfx (v0339). The upscaled textures and transparency alphas did not work properly until I ran inject.exe as administrator! So thanks for making me think about that!

I managed to get a copy of the GOG version and it all works good, including this mod! I'd remove my comment if ModDB had that.

So yeah, you did good, and obviously it's largely done by an algorithm but you did well doing so and I assume it has a few fixes and format corrections.
I love that it keeps the original style.

remember to check 3D Acceleration in setup! otherwise you might have the wrong resolution in the jkgm.json

I have, and it's still a black screen but with the the health and ammo monitors in the corners. it only seems to work when I have it off

update: whenever I try to boot the game up I get a pop-up from steam asking me for permission to boot up. when I do it redownloads jediknight.exe (despite my renaming the first to JK.exe) and plays that instead

(edit) update: I installed dgvoodoo and got 3d hardware acceleration working. still running into the same issue with the .exe though

Here follow my Steam guide for installation on Youtube: Youtube.com You should not need Voodoo the JKGFXMOD should already help with the 3D Accelerator make sure you change your resolution in the jkgm.json file. and run the game with the inject.exe not the jk.exe
