Nvidia and AGP

[nickhi]

I have installed the latest Nvidia drivers and all works fine. Are there any tools that show the AGP buss speed under Linux. I have the AGP 4x setting enabled in BIOS but Mandrake 8.0 tools report Bus type as PCI.

I run Quake 3 in both windows and Linux but under windows I get about 30-40 FPS more.

Anyone got any ideas how to improve the graphics performance ?

I think you may need to include the agpgart module in your kernel. Not sure. I haven't benchmarked my graphics and I dont have Q3 for windows.

If you are using the latest NVidia drivers you're doing about the best you'll do, assuming of course you followed their installation directions including the mods required in XF86Config. On my system, Duron 800@908 w/NVidia TNT2/64, I can see fps rates anywhere between 50 and 250. All depends on what I am doing and how much of the screen is being written to. GLgears is probably the simplest test you'll get for frame rate. Just run it from a term window, and it'll report the fps rate while displaying GLgears. You'll see the rate change with the size of the display window. When comparing Windoze to Linux, be sure to compare apples and apples (ie: full screen 1024x768 or whatever) on both OS's... Never made the Windoze/Linux comparison myself, but I find tuxracer at 110 avg. fps @ 800x600 is pretty alright by me.



Your system may be different, but try doing a cat /proc/nv/card0 and see if that tells you what you wanna know.



btw.. NVidia released an updated driver recently which has a few GForce2 fixes in it.

version 1.0 - 1512 are stable as a rock. I found that 1251 were a bit dodgy and 0.9 ones were a joke. I can play d3 demo at full spec and no flickering.

hey im not trying to cause any B.S. ...just trying to figure this whole forum out...should this not be under hardware or does it stay here as it is the "driver" prob...just trying to sort things out that is all guys :)
ooh by the way ther should be something in linux like windows display advanced fetures tells you all of that..including the clock speed of gf vid card/agp buss speed...overclocking etc...or is that what you were looking for ???

Nope, I think we've got it right. discussion is software/driver configuration.



And, nope, you don't get that sort of luxury, you have to do things like cat /proc/pci or lspci or other such neato commands to find out such intimate details. See, life with Linux is sorta like life with any good woman. You have to know how to find the right spot(s). Of course, she'd better be a good woman to put up with all of the cursing and swearing too.

oh ok..on both accounts :)

I see where you are coming from, but as this is a purely Linux driver question I think nickhi will get more of a response here.

sure thing i got it now :)

o.k. once again im opening my big mouth without knowing what im talking about...lol...i was reading in the agp mobo drivers...that for some strange reason the updates for this dont show all the advanced properties...ie overclocking the vid card..i got lucky once before i reinstalled and found the settings...anyway my point is if the drivers dont show the advanced settings for win98se...then maybe you are getting the same results no matter what the os is ???

[nickhi]

Thanks for the responses guys. Like Warlock I wasn't quite sure where to post this question, however .....

Have checked that the kernel module being used is the Nvidia NVAGP module and ran /proc/nv/card0 - response indicates that I'm at 4x, so I think that answers the driver issues.

I now just want to increase the FPS performance to near what I get under Windows.

I usually find my nvidia thingy under /dev/nvidia0 etc.
