try one of the early drivers that support the ti and go from there...

Yeah I have seen stability problems with drivers after 56.64 on a Pentium 3 system. You really should go for 45.23 or older.

Installed newest Drivers in WinXP (just testing -- for Win98 will use older ones of course) -- will try older drivers later..

Overclocked GPU core to 300 MHz via coolbits

doom3:
Disabled Shadows
Settings: Medium
Bump/Specular: On, everything else -- off

Significantly better performance (playable), 15-20 fps.

Question:

There still are temporary FPS drops when you open doors and enter large rooms.

Why does my FPS drop when I open doors and enter new rooms in games?

Chipset bottlenecking? I have VIA Apollo Pro 133T.
Or you think it's irrelevant and downgrading Drivers really should help?

All I want is smooth, constant framerate in NOLF on High settings, without these drops when I enter rooms. DOOM3 is just for fun.

Try without overclocking CPU and RAM... You can't do trouble-shooting when having parts driven beyond their specs.

40.72 (98)
Significantly better results. NOLF now can run at 1024x768x32 without freezes. Can even go up to 1280x1024 (at 16 bit though).

With OC, though.
Without OC, still better -- smooth gameplay at 1024x768x32.

No FPS drops with or without OC.

42.70 (XP)
DOOM3 still barely playable.

However, 3DMark2001 result is now 6999 (no OC)

(previous result: 7772 with 1133@1276 CPU OC) -- kinda comparable
With CPU OC, it's 8482 -- quite an improvement.

DOOM3 framerate is still worse than on GF2MX/P3-700 with newest drivers and DX9c. Strange.
Wonder how did this guy do it on Ti500: https://www.youtube.com/watch?v=uWNqDGDtMD4 -- probably they have Pentium 4 or Athlon XP?

I'm not planning to play DOOM3 on this computer, but this video just makes me envious.

Is this card a good match for a 1133@1276 Tualatin? Would 1400MHz version have been a better chioce?

Thanks a million.

Not enough RAM for the settings you use.

Geforce 2 MX does not have pixel shader support to it uses a simpler render profile. Geforce 4 looks much better.

See a Geforce 2 MX example here: https://www.youtube.com/watch?v=Zh4rbk6kjKo

He was using a Pentium 4 3.4Ghz.

Look here how a Geforce 4 Ti 4600 can run Doom 3: https://www.youtube.com/watch?v=p07Z_dXAv10&f … youtu.be&t=1533

Will 512MB be enough? Single stick, Hynix

I must have made a typo -- DOOM3 framerate is still worse than on GF2MX/P3-700.
So if I try with GeForce2 -- should I expect better framerate because of unsupported features? This P3-700 was my main system like 15 years ago.

Yes, at least for lower than high settings.

I was saying that you can't directly compare the 2 cards. That said a Geforce 2 MX will get you worse performance. Like in the video I linked which was maybe 13 FPS average.

You can also try running your Geforce 4 as a Geforce 2:

Open doomconfig.cfg file in the 'base' directory.

Change this line:

seta r_renderer "best"

to

seta r_renderer "NV10"

Still pretty bad performance -- but at least comparable to my P3-700/256/GF2MX system.
Even with 512MB RAM.

Probably DOOMIII requires significantly more powerful CPU with hyperthreading. And only then it will work fine even on GeForce2.

I guess I'll consider the original issue resolved. I'm happy with the GeForce Ti4200 -- even GTAIII and Vice City run without any issues -- unlike my P3700-GF2 system.

Thanks again!

Nope. It can barely use two cores. Game require Pixel Shader and Vertex Shader so GF3 is minimum and AthlonXP 1500+

Years ago i get ~10-15 fps on my C750, 512MB Ram and GF2MX-400

Try detonatros 45.23 or even older ones.

Partially fixed by changing motherboard to TUSL2-C. Significantly more stable framerate (~20 fps), and almost no squares in shadow areas (still decided to turn them off).
There are FPS drops, but not as random as when I was using 6VTXE.
Probably VIA Apollo Pro 133T chipset cannot handle such amount of load.

Kinda offtopic -- just showing off.
HL2 perfectly playable at stable FPS (dxlevel 7) at 1920x1080x32 without significant slowdowns (only when entering outdoor areas).

Though I haven't tried the previous board with HL2 (it's currently sold to a guy who's going to use it with Win98 and Voodoo4), I guess I'd have had much more unstable gameplay in HL2 on it.
Oh yeah, and the sound now works in WinXP.
