Problems on GeForce6

[EgonOlsen]

I have some problems with LWJGL (0.95 and 0.96) on GeForce 6X00 cards (in this case a 6800 Ultra and a 6600 GT) using the latest drivers as well as an earlier version. I've verified this on three machines using Java 1.4.2 and 1.5: All three machines can't do windowed mode correctly. LWJGL crashes with an Exception:

Exception in thread "main" org.lwjgl.opengl.OpenGLException: Out of memory (1285)
        at org.lwjgl.opengl.Util.checkGLError(Util.java:56)
        at org.lwjgl.opengl.Display.update(Display.java:515)

or the window opens, the mouse becomes very very jerky and nothing happens...just a white window and a jerky mouse.
This problem doesn't occur on a GeForce4MX and a GeForce 5700LE using the same (latest) drivers. But every 6X00 that i've tested LWJGL on has this problem.
Any suggestions or can anybody else verify/falsify this?

Paradroidz works fine on my new 6600GT - ForceWare 71.84 in windowed mode

That's the same version that is giving me the problems... :?: I've ordered another 6600GT as a replacement for a blown up 9700pro...i'll do another test when it arrives.
BTW: The Windows desktop flashes when starting any Java application (may it be webstart or whatever) on the "faulty" machines...maybe that relates somehow to the LWJGL problem, but i really don't know what is causing this...
I even did a clean install of XP, the drivers and Java 1.5. and i still had the problem. Strange...

Edit: Any idea on this out of memory exception?

tried running 16 bit depth on desktop and then 32 in paradoridz - still worked like a charm.
Can you run other OpenGL applications?
does it only fail in windowed mode - and not in fullscreen ?

Yes i can. Just LWJGL stuff fails (not only jPCT related...all the lwjgl tests are failing too). It works to a degree in fullscreen. Sometimes is shows the same jerky mouse behaviour and doesn't render anything albeit the application is obviously running. ALT-Tabbing to the desktop and back solves the problem. But sometimes, it just works. Windowed mode always fails. To clearify this: This happens on three different machines, not just one.

It sounds like you might have forced AntiAliasing enabled in the driver settings. Make sure you try turning leaving both AA and AF settings at "Application Controlled" and see what happens.

I had this idea too (because this setting causes problems with Java on my ATI machines, so i'm used to it), but it doesn't change anything...the problem remains.

Have you tried initializing the Display.create() without a custom pixelformat? I ask because I also have a 6600GT, and I seem to be running my games just fine.

Can't remember if i tried that with Display, but i definitely tried it with the new AWTGLCanvas...doesn't work. Does Paradroidz work for you in windowed mode?

Edit: Tried the AWTGears demo once again on one of the machines...i got 1 fps, extremely jerky mouse behaviour and a reboot after some seconds... :cry:

I won't be able to test it on my 6600GT until I get home from work today, but it did work fine on my Geforce 5650 in windowed mode.

Try this one: //www.tommytwisters.com/twisters/twisters.jnlp

Set it to windowed mode and hit "apply" to see if it works for you.

BTW, is Paradroidz using lwjgl? The one I tried mentioned something else. Do you have a link to the one you're talking about?

Yes, it does use LWJGL if you configure it to do so (default, OpenGL Renderer). However, i've changed AA to "application" once again and now it works. So either i haven't done that correctly the last time i wanted to test it, or...or i'm just stupid. Anyway, it behaves similar to the ATI now: Doesn't work with forced AA, works with "application controlled". But it think that's more of a Java problem then LWJGL's...it's annoying anyway, because i'm always forcing AA in the drivers to play my games.

Edit: The link to Paradroidz can be found below... :wink:

Ah ha!

EgonOlsen,

I can confirm I am having exactly the same problem as you described when AA is forced in the the drivers (strangely 8xS mode seems to work great except for the expected performance hit).  This has been occurring in both 0.95 an 0.96 with the latest and previous NVidia drivers.

I have not tried using a pixel format with multisampling enabled.

Specs:
Windows XP SP2
P4 3.06GHz (HT disabled)
1 Gig DDR333 RAM
NVidia GeForce 6800GT

All my other OpenGL games and apps work fine.
