Ok, I updated my Nvidia drivers to 53.03 and now the demo works. Excellent work Tom, it plays really smoothly. I couldn't get fullscreen to work though, it crapped out when I tried.

Damn drivers. It's a wonder that PC games work so well most of the time!

[tom]

Glad you finally got it working

[erikd]

I'm getting a weird texture and a BSP hole:

I'm getting this yellow texture + BSP holes everywhere I think should be a sky box.

Yes. Got some issues with sky shaders at the moment. It will be fixed. Until then, just try to ignore it

The previous version worked in windowed mode, but with the  latest version, I get:

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15

I'm runnning 1.4.2_04 on XP

[darcone]

Funny that the doors open when you shoot at them Other than that, looks really really great!

[Morgrog]

Really really good stuff, I get some really good fps too!

If only I could play for more then 5 secs at a time :|

it crashes to the menu after a few seconds...

gnah well, still looks really really good

[erikd]

Did anybody compare this with Quake 3 yet, performance-wise?

Erik

[tom]

I've done a couple of tests, and the fps is within +-15% depending on where you are and where you are looking.

But it's not a completely fair comparison as the q3 renderer does a lot more stuff like lighting entities, loding bezier surfaces, tesselating fog surfaces, doing multilayered sky etc. Also, we have vbos now wich improves performance alot.

[Abuse]

Still isn't working here

Athlon 1.33, 512ddr, GF2gts 32mb (latest drivers 56.72), WinXP.

I got it working once, out of the 4times I tried, don't ask me how or why, all I was doing was hammering the copy button on the java console window (to make sure I didn't miss the error) and it worked! (although, ingame it crashed as soon as I fired after picking up the grenade launcher)

Havn't managed to replicate this however.
Normally I just get a black framed window, desktop changes to the fullscreen gamma settings, it then bombs out with this :-

So this makes the 'java part' (as opposed to the accellerated video part), a lot slower than -15% from the C counterpart doesn't it?
Any optimizations still possible in the java code?

[2late4u]

it crashes to the menu after a few seconds...

why???

[tom]

it crashes to the menu after a few seconds...

I don't know the exact reason behind it, but it's a network problem. The game quits to the menu if the server is timed out. Meaning the client don't recieve any packets from the server within a 5 second timespan.

The next version will not quit to the menu, but instead show a warning message in game.

What system are you running on?

So this makes the 'java part' (as opposed to the accellerated video part), a lot slower than -15% from the C counterpart doesn't it?

Kind of hard to tell. I don't know how much impact the missing features would have on the fps. How much faster would q3 be with vbos? Who knows.

Any optimizations still possible in the java code?

Sure. I've only optimized the level renderer. The entity renderer could be optimized. It currently don't do any state sorting. It uses opprox 15-20% of the frame time. The bezier collision detection is also very slow, as it generates an insane amount of brushes and planes.

>The bezier collision detection is also very slow, as it
>generates an insane amount of brushes and planes.

Q3 uses subdivisions 80 for the physics part regardless of the visual subdivision setting. The bounding boxes of the players are axis aligned BBs. The collision detection of player vs patch was optimized several times and now it only seems to kick in whenever you are sliding along a curve.

I just thought it's a good idea to point that out

i have windows XP

[EgonOlsen]

I don't know the exact reason behind it, but it's a network problem. The game quits to the menu if the server is timed out.

Don't count on it. I get the same behaviour but it seems to be caused by the org.lwjgl.opengl.OpenGLException: Invalid operation (1282) stuff (as mentioned before in this thread).
Win XP, ATI Radeon9700pro...maybe it's a problem with ATI!?

[princec]

No, it's more likely that a few org.lwjgl.opengl.util.checkGLError() calls are needed to narrow down what function is being called with the wrong parameters or at the wrong time.

New version up which tries to fix some of the reported problems.

First off I've removed drawRangeElements alltogether. They seem to cause a native crash on some nvidia cards. In particular those with the latest drivers. This I hope will fix the "it craps out before the menu is shown" bug.

I've tried to fix the "It returns to the menu after a few seconds bug", by ignoring OpenGL errors. Hopefully the errors are not critical and the game will keep on ticking.

So if you've had any of those problems, please try again and report back  

[Abuse]

yay, works now - though it still crashes when u collect and try to fire the grenade launcher =)

Windowed mode 640x480 I get ~145fps.

:edit:

scratch that - it crashes after roughly 6seconds,
which is coincidently the amount of time it takes to go through the tp, and collect the gren. launcher =D

There is no error msg either, it just dies and vanishes - along with the console.... leaving the gamma set horribly high

Can you put a shutdown hook to restore the gamma/contrast/brightness in the event of a crash?

[deepFlame]

Yepp, I've got the same problem.

[tom]

Can you put a shutdown hook to restore the gamma/contrast/brightness in the event of a crash?

Could try. However, what you are seeing is native crash. The javadoc says that there is bo guarantee that the shutdown hook will run if the vm is aborted. Anyone have any experience with this?

You can also adjust the gamma in the menu before entering the game. That way you can have a quick test with normal gamma values. Just to make sure it don't hang.

[Luke]

Just to say the problems I reported all appear to be fixed in the latest version.
