Hello,

after not having played for about a year, I recently started playing openarena (ver 0.8.8 ) again.

For some reason the 2D sprites in the game are now all rendered with extremely low resolution. I don't remember this problem existing when I played the game before.

This affects mostly the HUD, but when enabling simple items those sprites are also affected. I have also noticed that using any resolution lower than  1366/1360/1280 x 768 makes the problem worse.

Here is a screenshot (without simple items):

I'm playing the game on a Fujitsu Lifebook AH530, Windows 7 64-bit. The computer uses an intel core i3 and intel graphics media accelerator HD.


I found another thread on this message board with apparently the same problem:
http://openarena.ws/board/index.php?topic=3988.0

Sadly, the suggested fixes (changing the value of /r_picmip to 0 and/or resetting openarena config as described in the thread) don't work for me.


Thank you for your help.

The only cause of this would be the graphics driver automatically generating mipmaps and having a heavy bias (hence the lower resolution affecting it more).  Those sprites and other 2d elements in particular have nopicmip/nomipmaps properties in their shader so they should never EVER be blurry or even have a mipmap for them.  They should be sharp even at a higher picmip.


Since it's an Intel graphics problem, have you tried any GL-to-D3D wrappers such as GLDirect and QindieGL?


BTW the only hardware I personally tested to have a problem like this is Matrox G100A which has a serious mip selection issue, however even that 1998 4mb card can display the 2D graphics sharply.

asking when OA3 will be done won't get OA3 done.
Progress of OA3 currently occurs behind closed doors alone

I do not provide technical support either.

Can I suggest trying to update video drivers?

Hi, thanks for your quick responses.

Copying the opengl32.dll from GLDirect into the openarena directory did the trick. Everything looks fine now.  Cheesy

I tried out the opengl32.dll from QindieGL as well but the game won't even launch with it.

Many thanks.

Regards,

Glad it works Cheesy


To think Linux doesn't have this option available gives all the more reason for having a software renderer....

You can still use DX/D3D via WINE if you please, not that it makes things any better Wink
