Nvidia/ATI vs. Vesa drivers

I have an older Nvidia card (GeForce 6150SE nForce 430) on board, and i find that the speed is AMAZING faster with a vesa driver than with a Nvidia driver...only draw back, NO 3d Acceleration! however that only effects google earth or compiz. I don't use compiz but i do some globetrotting on G-Earth. Does anyone know of a X.org driver (like vesa) that supports acceleration? not much info online. Though i'm still checking...perhaps someone else has had the problem as well. All i know is that vesa is MUCH faster than Proprietary Nvidia drivers. MiCK

Intel xorg.conf Configutation

Intel Corporation 82865G Integrated Graphics Controller On an intel desktop pc, testing onboard graphics & sound. The set up is dual boot, hda1 is my general desktop used for mail etc., I built the image using pdk and it's based on "hardy" upgraded to intrepid (kde4). hda2 is used for testing installs, right now, 3.0 alpha "hardy". The strange thing is the default xorg.conf's are the same, both ubuntu defaults. Yet what I'm finding is the hybrid xorg.conf I've created to suit the intel graphics driver works really well on hda2, but fails completely on hda1. Wierd? same distro, same computer, one works and one doesn't? Tweaking the default xorg.conf Module/Device/Monitor/Screen sections makes a vast difference to the graphics experience here. As always backup your original file before you begin testing. nVidia/audio performance: Finding the driver that works best with your card is the key. Newer is not always better, checkout the mailing lists, you will find users who are having problems with newer drivers having better results when they use an older driver. Cheers! dave

Speed is amazing!

I'll look into getting something of that sort..but frankly my focus is on testing this concept with audio production and not graphics. so far i am very pleased with the alpha and it's peformance. Better yet, I am even more please now that i have "rolled back" to a vesa driver because of the new kernel. even my browser(Opera) is screamin' faster with the vesa driver. I may just have to say good-bye to Google-Earth altogether! I'll test the RT and Jack response to this driver in relation to x-runs etc. and report back. I have suspected that (hearing in and around the community) proprietary drivers drink your resources and add to problems in core functions. perhaps this could settle a bit of latency/x-runs/performance issues. won't know till i try it out. thanks MiCK

The funny thing is that the Vesa (and nv) drivers perform better under RT kernels with on-board GPU's because they use shared RAM, and have to compete with audio for bus time. GPU loses every time. If you want to see something amazing, get a same (or lower) stand alone GPU and see how it flies solo... My 6200 is more than twice the speed of my on-board 6600 in RT kernel conditions.
