Jedi academy black screen

[Onysfx]

Already did that. Infact, that's what caused my screen resolution problem and jka still didn't work.

 

(Did a system restore to undo the driver screen resolution problem) I don't think the problem has to do with drivers.

[CaptainChar]

does your video card have a control panel?

[Onysfx]

If I install the the latest driver, I will get the catalyst control center. Although, it does cause problems with the screen resolution thing, but if it can possibly fix jka, I'm open to suggestions.

[CaptainChar]

have you checked if the catalyst control, has a game profile thing? My old Nvida had specific settings per game, not sure if this still exists or not in machines, but worth to look around in the 3D rendoring settings for the card

[Onysfx]

No it doesn't, its not like other catalyst control centers iv seen on youtube and in pics, it doesn't have many options, let alone the...game profile thing...

[minilogoguy18]

Before you're updating drivers are you uninstalling the old? Sometimes there can be conflicts with bits left over from the old driver.

[CaptainChar]

nvidia is famous for that, the driver updates for them, allow a complete removal of the former driver, that can be an issue as well

[Onysfx]

Hey.

 

I just tried playing Elite Force (as it also runs on the q3 engine) to see if its just jka, and the exact same thing happens. Black screen with sound.

[MUG]

Yup, sounds like your video card/driver doesn't work with q3 for whatever reason.

[Onysfx]

sniff sniff...is there any way around this? Or is it goodbye jka?

 

Darth Sidious: Oh, I'm afraid the ATI Radeon will be quite corrupted when jka arrives...heheheeheh...good....

[tritoch]

Sounds like an ATI extensions problem.

 

Here's one possible fix from the Lucasforums. Seems like the post has been updated in 2012, so it might work. (http://lucasforums.c...ad.php?t=206018)

 

Also, as i recall, the 10.4 fix worked as long as you used 10.x drivers. So, you might get it to work if you downgraded from 12.x or 11.x drivers to 10.x drivers. There's a more detailed post about it at The Jedi Academy site. (http://www.thejediac....php?f_id=17700)

 

Hope at least one of them works.

[Onysfx]

Thanks for your suggestions tritoch, but I've already done all the things you have suggested.

 

As well, the two posts talk about jka crashing. Jka does not crash for me. Black screen with the sound still working.

[Onysfx]

Hey, sorry for double post, but I have confirmed that this must be an OpenGL problem stopping jka!

 

I just recently got the original half life, and I had the same black screen problem as jka! So therefore, I tried running it in a window, 256 colours, and some other settings. The game then had problems with the rendering, so it then said it would render in "software mode". I then found out that it was originally rendering with OpenGL! I disabled all those other settings like 256 colours and stuff, and now the game works just fine. So therefore comes the question:

 

Is there a way to run jka without OpenGL? Perhaps D3D or something?

[CaptainChar]

open GL is usually better then direct3d these days, but sometimes newer cards drop elements that enabled "legacy modes" for older applications, ive yet to try JA on my netbook yet, as it uses the Intel Chipset for video, but the HDMI out is handy, the machine wont run some older game, they just explode the models, but DX10 type games seem to work fine, DX9 or DX8 seem to screw up royally for me, the hardware is openGL based in my case. so I maybe facing the same issue as you soon

 

It has to run JA since I can map while im not home, and its not useful if I cant test the work for me

[eezstreet]

D3D can't be used with JA; Quake 3 and its derivatives all use OpenGL. I think what's more likely the case is that your video card's drivers dropped support for the old and deprecated functions used by Q3 games.

Sounds like a serious issue.

[Onysfx]

Hmm...so what can I do about this? I know updating drivers won't work (creates even more problems anyway) ...is there even anything I can do? This doesn't just affect JKA, it's affecting every game that uses OpenGL.

Is there any kind of workaround?

[CaptainChar]

oddly enough a new acer netbook, with intel HD 3000 series video chipsets, plays JA fine, without any issues, so this issue does puzzel me

Perhaps try older drivers then - ones that came out nearer the ja period, so circa 2004-5?

[CaptainChar]

another option is to remove the driver completely and use a driver scrubber to remove old driver isntallations, then reinstall your driver from either driver disk or from the site of manufactor, Nvidia is famous for having to delete older drivers to install newer versions,

 

i'll be looking into the matter though since now I see it as a challange, and I like them when it comes to pc diagnostics

 

good ol run command and the dxdiag will tell you what all the specs are, model, make etc what your current video driver is etc

give that a run and copy and paste or post a screen of what the system says the specs are.

/r_atihack 1

Try this in the console. Then do a vid_restart. If that doesn't work, turn it back off and vid_restart again.

[Onysfx]

Nope, still didn't work. My computer just doesn't seem to like openGL or something. I still don't understand how I got Star Trek Elite Force work without the black screen, considering they use the same source engine.

[eezstreet]

Tried running in windowed mode?

[Onysfx]

Yep, just did that. The whole windowed screen is black. Still hear all the sounds, can open the console, etc, but I just don't see anything. I'm honestly not sure what the problem is. Is there any way I can attach a screenshot?

 

EDIT: Oh, just to be sure this isn't misinterpreted, the whole screen is black, even when I open the console I can't see it. I can't see nothing, not the mouse pointer, menu, logo, NOTHING.

 

EDIT 2: Theres another thing you should know. I had to use GLDirect for jedi academy to run on my old laptop, and am still using it here. Without it, elite force won't run either. 

 

EDIT 3: Does jedi academy use vertex/pixel shaders at all? Are they required to run it successfully?

[Raz0r]

Try not using GLDirect, and no, new style vertex/fragment shaders are not used. ARB shaders are.

[Onysfx]

Already tried that Raz0r, still the same thing. A black screen with sound...hmm...well at least now I know I don't need GLDirect to run JKA on this computer...but it seems elite force won't run without it...this is getting weird. Is there anything else I can do? I've tried disabling the video card in device manager, still doesn't work. 

 

Hmm...just some more info for everyone:

-In project64, if I use the Glide64 (openGL) plugin, the emulator will crash.

-As well, when running the visualboyadvance emulator, if I select openGL as the render method, the emulator will crash.

 

But even with these problems, it still doesn't explain how I am able to get Star Trek Elite Force working when it uses the quake 3 engine just like jka..

http://jkhub.org/topic/2255-whats-with-my-graphics-card/

I created a new topic for the elite force thing, I should have posted it here though.

 

Is there anything else I can do?
