TurboGL and Half-life decal problem

[Johnny Ray]

Hi,

Was really enjoying Half-life with my G400Max and PowerDesk 5.25 drivers on my PIII 500 MHz. Absolutely no problems. Just had to try the TurboGL and 5.30 drivers, and now I'm having a decal problem. They flicker, fragment, dissappear, etc. The decals display fine with D3D and 5.30 drivers. My Half-life autoexec.cfg file is essential the one Kruzin has posted previously:

gl_ztrick "1"
gl_dither "1"
gl_polyoffset "4"
gl_lightholes "1"
gl_keeptjunctions "1"
r_decals "1"
r_drawviewmodel "1"
r_shadows "0"
cl_himodels "1"
gl_texturemode "GL_LINEAR_MIPMAP_LINEAR"
brightness "2.5"
gamma "3.0"
gl_playermip "0"
gl_picmip "0"
gl_round_down "0"
gl_texsort "1"
gl_overbright "1"
gl_palette_tex "1"
r_decals "400"
scr_conspeed "8000.00"
r_mmx "1" //added 9/18/99 JRC
s_a3d "1" //added 9/18/99 JRC
joystick "0" //added 9/18/99 JRC
s_eax "0" //added 9/18/99 JRC

I've tried different gl_polyoffset values, all leading to the same results.

I'm not sure what to try next. The TurboGL manager says all is fine. Thanks for any suggestions.

I would first try turning off the z-trick. Then try playing with texsort.

Good luck,
Wombat

I would not change gl_texsort.
gl_ztrick may or may not do anything.
The one I would mess with is gl_polyoffset. Try anything from -1 to 12. You can use any value, including decimals. (but you already tried that)

Also, try enabling 32bit zbuffer in the advanced powerdesk options if it's not already...

Looks great here. Figured out how to get V2 and G400 MAX to coexist, too. 1152x864 is perceptually smoother than 1024x768, don't know why (and no, 1024x768 isn't burping - fixed that one).

I can get all my specs if necessary. I did turn off ztrick, I turned on paletted textures (had them on from the G400 Tweak util), and I left shadows of? on? r_shadows 0, whatever.

Anywho, got more testing to do.

I have damage images (blood, burn marks, etc.) flicker and are now missing entirely with 5.30. I also lost the fog effect in water you see in the Well map. Tried 32 z. Any suggestions would be appreciated.

[Buckaroo99]

Disregard previous post. Polyoffset worked for me.

Hl still needs a bit of work--a ceilinglight which is solid on a V2 comes'n goes now depending on the players position . Mostly it is half there.Colours are better though and speed is fine .
Textures in Q3 need work too. Max textures are unplayable here .

Troop-
Did you turn on 32bit z-buffer?
I had a simialr problem with OGL, where certain lights and sighns at a distance would "flicker" in and out of view. 32bit zbuf fixed it right up...

[troop]

Kruzin ( "for a bruzin" me dad used to say ).
Yes I use 32bit zb.The light is in crossfire,
main courtyard, hallway leading to the 2 rooms under the main second floor , at the end of the hallway , there's a light on the ceiling. Turn right there to get to the platform that goes to the second floor. See it ?

No, I don't see it....but I'm also only using the regular ICD...no P3/K7 here...

[Wombat]

Even with a 32-bit z-buffer, the light should still flicker if z-trick is true. Try turning that off.

Thanks for the suggestions. I've tried them all, but nothing improved the situation. I did do a complete uninstall of PD 5.30, and re-installed 5.25. The decal problem is still there, but doesn't seem as bad (no change in autoexec.cfg). Uninstalled 5.25 and went back to 5.30 (heh...if the problem's there with both, I might as well get the extra FPS!). Now, no decals at all. The autoexec.cfg does have r_decals "1", so they should be on.

Any other ideas?

Thanks,

John

[Kruzin]

r_decals "1" means ONE decal will be displayed, until another one is created.

try r_decal "400" or something...

[Johnny Ray]

Thanks Kruzin...

I thought r_decals meant decals on ("1")or off ("0"), and mp_decals was the number of decals displayed. I'll give it a shot.

Originally thAts how you would enable/disable decals. however, in newer releases, they put a number on them instead of disableing/enableing them.
