Poor OpenGL performance with my laptop

Hello.

I have installed Archlinux on my nvidia desktop computer and I can play opengl games smoothly. But the problem is with my laptop. I remember, long time ago smile, when opengl ran pretty well with linux compared to windows. Since one month ago, I've had windows and Arch on my laptop, when I tried to play Openarena, it ran much better on windows than linux, what has happened to intel driver? Now I only have linux and want to continue playing and it's impossible with that performance.

I've read many posts and I've failed in my purpose, I'm missing something...

$ lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

Thanks in advance.

Re: Poor OpenGL performance with my laptop

Are you using the intel driver?

Exactly what is the FPS? Also, xorg.conf.

I'm not using any xorg.conf. I don't know exactly FPS, I can try a benchmark so you can see.

Thanks.

Are you using KMS? If so, I found this.

That's really outdated and not only not necessary any more, but might in fact break your system if you do something wrong.

KMS is enabled by default.

Yes, KMS is enabled. I've read  that the better solution is to downgrade some xorg related packages. Is it impossible to use intel driver on 3 or more years old laptops? I mean, with good performance.

Well, downgrading is probably the best solution for now. It's possible to use the intel driver for your laptop(most likely)

Unfortunately  yes, I have seen since I use linux (like five years) that once a intel video card is not supported any more there is no going back to its optimum state, also the problem with downgrading packages is that at some point you would not be able to update other software any more with out issues.
