certain kernel configs for more powerful games

[janga8]

Hi all, new to Gentoo but managing, and so far I love it!
But I only have a weak laptop for now and cannot afford a better computer.
Unfortunately it is using Intel integrated graphics and they are terrible

My favorite game for the moment is TF2, and when i have run arch and Debian in the past it was, well playable and i averaged 20 FPS. Gentoo is just bellow the line that makes it playable as it is at around 10-15 FPS.

I read somewhere that a custom kernel can increase FPS (first install, so I used gen-kernel). What options should I use in USE variables and any kernel drivers/modules that I should/shouldn't use for a gaming computer.

Also disabling some unused modules for gaming (wifi, i use it but use Ethernet when gaming) is useful for gaming but not otherwise. So is it possible to have two kernels to interchange between using

I've disabled and built out many modules out of my kernel, the performance benefit was not that significant, at least not significant enough to impact my gaming experience, I doubt this approach will improve yours.

eselect kernel set sets the kernel sources in use(in case you have installed several kernel sources), just the /usr/src/linux symlink.
I believe your configuration is solely responsible for something like that

I'd start by checking if hardware rendering is enabled:
#glxinfo | grep rendering


you also should keep an eye out for use flags like opengl, vdpau(if your graphics card supports this feature) that more or less enable hardware acceleration as well
if you have the energy for it, you can use
$equery d <package name> to check the package's dependencies and track the use flags on each dependency

good luck

Ok then, do you/anybody know how to get FPS increases in general and in TF2?

Thanks

[Adel Ahmed]

make sure hardware rendering is enabled first, if it isn't you'll gain a massive FPS gain by configuring hardware acceleration

Ok thanks i ran

This really isn't hard information to find: http://wiki.gentoo.org/wiki/Xorg/Hardware_3D_acceleration_guide

Apologies if I take a while to respond. I'm currently working on the dematerialization circuit for my blue box.
