nVidia 8000/9000 Series Performance Issues

[NvFuchs]

Because it is a hack which should, with sane xorg options
and IPP, not be necessary.

Sorry for the naive question but i'm wondering, does the nvidia's guys read this board or it is just for users?

[NvFuchs]

They do, and they also reply from time to time.

Most of them (but not all) have the nvidia logo as avatar,
so finding them should be no problem.

I have a 8600m gt on a laptop.
I've enabled some options in xorg.conf that improve performance but i want to know a correct xorg.conf for my video card.

I've also a 8600M GT graphics card, this is the relevant performance options in my xorg.conf, I don't know if they're optimal though:

Section "Device"
	Identifier	"Device0"
	Driver		"nvidia"
	Vendorname	"NVIDIA Corporation"
	#additional settings
	Option		"NoLogo"	"true"
	Option		"RandRRotation"	"true"
	Option		"AllowGLXWithComposite"	"true"
	Option		"OnDemandVBlankInterrupts"	"true"
	Option		"NvAGP"	"0"
	Option		"DamageEvents"	"true"
	Option		"UseEvents"	"true"
	Option		"PixmapCacheSize"	"200000"
	Option		"AddARGBGLXVisuals"	"True"
	Option		"TripleBuffer"	"True"# Experimental
	Option		"BackingStore"	"True"# Experimental
	
EndSection

I'm trying your options now.i see that you doesn't use Option "RenderAccel" "true".
Do you use compiz? It always goes smoothly?

In my xorg log:

(**) NVIDIA(0): Enabling RENDER acceleration
(II) Initializing built-in extension RENDER

So it's enabled automatically. I don't use compiz but I use the built-in composite effects in xfce.

I have 3 xorg logs in /var/log:

Xorg.0.log ,Xorg.0.log.old, Xorg.20.log.

I see in xorg.0.log: (II) LoadModule: "type1"
(WW) Warning, couldn't open module type1
(II) UnloadModule: "type1"
(EE) Failed to load module "type1" (module does not exist, 0)

Ok i see that the Xorg.0.log is the latest.

In compiz i have to use the option loose binding.

Thas has nothing to do with what's being discussed here. It's a harmless error, related to fonts.

thanks for answering.

The next question is, have they ever said anything about the 2D rendering problems (resizing windows in qt 4.3 and 4.4 based apps, compiz, etc.)? Is there a bug tracking system that users can browse? That would be useful.

the link takes me to this same discussion, who is the nvidia guy? I can't see any nvidia logo

AaronP is one of the guys.

I don't play online at all, and there's no cap. It's ridiculous... I get 700 FPS and higher in some places and it starts to really screw up when that happens. It feels like I'm slipping on ice or something. It's even worse now, with my 9800GX2. (previous card was an older 8800 GTS 640 Mb)

At 60 FPS (as a result of vsync) the game is slow. I can't react fast enough and I get slaughtered by the bots playing instagib. 85 FPS would be good, but my LCD is 60 Hz at 1280x1024.

Underclocking the card before playing UT2004 has proven to be the best solution for me, such that the FPS stays roughly between 90 and 300 depending on map. Thanks for the reply, though.
