Now that my problem with console-switching has been solved, I decided to push my luck and get acceleration to work with my Nvidia GEForce card. As instructed in NVidia's README, I installed the v1251 NVIDIA_GLX.rpm package. I also called switch2nvidia_glx and ensured that my XFree86Config file contained: "Load glx" in the Module section "Driver nvidia" in the Device section I've also installed the v1251 nvidia kernel module NVdriver in /lib/modules (a few levels down). Nonetheless, when I run "gears" I get only 642FPS rather than the expected 1100. Are my incantations insufficiently pleasing to the gods? If so, what need I do to appease them? Paul
hi paul, is the module "NVdriver" loaded into the kernel (not xfree) ? are you using the linux-own agpgart support or the one from nvidia ? greets, chris Am Sonntag, 8. Juli 2001 02:00 schrieb Paul Abrahams:

Dunno. How do I find out? Which one is the right one, and where might I get it? Paul
re, check /var/log/messages (or in the console window in x that starts up first by default) if there is something reading : Jun 30 09:56:35 nervous kernel: NVRM: not using NVAGP, AGPGART is loaded!! this indicates that you are using the kernels agpgart. i have thrown it out by compiling my own kernel (which i always do). do so by disabling the option "/dev/agpgart" under the section "character devices" as module it is called "agpgart.o" the nvdrivier has its own, i found out it is more stable with the nvdriver's agp support. but as always, "you mileage may vary" greets, chris Am Sonntag, 8.

Paul. Try: Option "NvAgp" "1" To use the nvidia's agp drivers, and run in 16 bit, 24/32 is a framebuffer and degrades performance. Curts On Saturday 07 July 2001 19:00, Paul Abrahams wrote:

I'm confused. Are you saying that installing this option will degrade performance? Or are you saying that "NvAgp 1" uses 16 bit buffers while other NvAGP values use 24 or 32 bit buffers and degrade performance? Is NvAgp documented anywhere that I can read about it? Paul
Sorry, 2 different issues. A) set the agp option as noted. B) run X in 16 bit colors because 24/32 bit colors requires a framebuffer (this is independent of the agp setting). I wanted you to try both these varaible to help improve the performance. The essential on is not run in anything higher than 16 bit. The agp setting is to help with further optimization.

A) Note that NvAGP is the default. You only have to set this if "1" (the nvidia AGP handler) isn't working properly. B) I believe 24 bits are accelerated, and that only 32 bits use the frame buffer The IgnoreEDID is only for when your screen reports wrong data. Most newer monitors don't need this.

You can check the settings your nvidia card is using by cat /proc/nv/card0 (or whatever number your card is in your system) my system reports ----- Driver Info ----- NVRM Version: 1.0-1251 ------ Card Info ------ Model: GeForce2 GTS IRQ: 11 ------ AGP Info ------- AGP status: Enabled AGP Driver: NVIDIA Bridge: Via Apollo Pro KT133 SBA: Supported [disabled] FW: Unsupported [disabled] Rates: 4x 2x 1x [4x] Registers: 0x1f000207:0x00000104 And I get 2800+ fps with gears at 1600x1200 at 16 bits colour depth Regards Anders

Is it possible that my board is only capable of 640 frames per second? How might I check that out? My default depth is 16; I've experimented with various nvagp settings and they make no difference. Paul

Funny, the new nvidia drivers work better at the higher res. I get 1500+ at 1024x768. I have read posts on other NG's about the higher performance at higher res. I plan to buy a new monitor soon and wonder what, if any, performance boost I'll get. Also, your runnig at 4x agp and I only have x2 but 2800+ fps is very nice.

There are two issues I can think of off hand. One is to make sure you're using nvidia's agp handler.
I just recompiled the Linux kernel, eliminating agp support from "character devices" in the configuration. Now I, like you, get NVIDIA rather than AGPART as the AGP driver. And that doesn't solve the problem.
The other is that you're using different module versions for X and the kernel. The readme expressly says that this won't work. This could very well be the problem.
Could be. Maybe there's something I'm missing about the NVidia kernel files. They come in three forms from the NVidia website: 317298 May 21 14:16 NVIDIA_kernel-1.0-1251.src.rpm 1405550 May 21 12:50 NVIDIA_kernel-1.0-1251.suse71.i386.rpm 315616 May 28 21:45 NVIDIA_kernel-1.0-1251.tar.gz As I remember, I used the source files and did a "make" because the NVidia rpm was for kernel 2.4.0 and I was running 2.4.4. I think I tried the other files earlier but something went wrong with them. Paul
