opengl extremely slow after newest nvidia driver

On XFCE, after installing nvidia v295 released on 4/11 i think (kmod) my screensavers and glx gears went under 1 fps in full screen on a 2x64 Athlon and a series 6 GeForce card. Flash animation works fine though. Tried to remove nouveau from initramfs with

mv /boot/initramfs-$(uname -r)-nouveau.img /boot/initramfs-$(uname -r).img
dracut /boot/initramfs-$(uname -r).img $(uname -r)
# removed "rdblacklist=nouveau nouveau.modeset=0" from GRUB_CMDLINE_LINUX
grub2-mkconfig -o /boot/grub2/grub.cfg
But after dracut nothing happened, i did not get my prompter back. Do i need to replace above uname with something else?

One question, if i have after updates, 2 different kernels in the menu and each of them is working with a different version of nvidia, and only one nvidia drive in the initramfs imge, do i have to keep nouveau in that image so i can fall back onto it if i choose to load a different kernel?

Ok. That's great. I've done two or three things simultaneusly and i don't know what fixed it. First i choose to install rpmfusion free and nonfree repos with rpm instead of yum. But i updated them with yum. When i tried to install kmod-nvidia, it told me that i have a newer kernel, 3.3.1-5, which honestely, i can not tell anymore cause i didn't pay attention to the last digits. So i went with akmod and voila, it worked. I went from the wimpy 60 FPS with glxgears on my GeForce 6150SE nForce 430 with the nouveau driver to the stellar 90 FPS. But because what i found out earlier, that i will always have two drivers in the initrams and shortened the boot time and some 100 more MB occupied on the hard drive which will constantly grow with the updates, and because i was expecting more from the nvidia driver, now i give up and go with nouveau. Period.

Re: opengl extremely slow after newest nvidia driver

There is a known performance regression in the binary drivers for older GeForce models
like yours. Revert back to 295.33 until they fix it.

Can you help explain this move to me? My fedora acts the same way. I'd like to revert back to this driver hoping that it would fix the problem, but I'm really new to linux, can you give me the baby-steps?

In reply to #6:

This did the trick for me at Fedora 19 and NVidia 319.32.

Tnx a lot.
