Re: [Trisquel-users] Full screen at full resolution slow for some games

Mesa is not a driver but rather an abstraction of OpenGL that sends calls to  
the appropriate driver if possible or does it in software otherwise. You have  
the driver for your GPU installed; there isn't even a proprietary driver that  
exists for Intel integrated GPUs. But it cannot do everything in hardware, a  
physical limitation of what the GPU can do (the hardware is designed for a  
particular OpenGL API and what that particular GPU supports is an older  
OpenGL version), so some things have to be done in software. Possibly a lot  
of things. This leads to poor performance because rendering OpenGL without  
hardware acceleration takes a lot of processing power.

In short: what you are facing is not a software problem. It's a hardware  
problem. The only way you can solve it is to get a newer GPU, so you might as  
well give up on the idea for now. The best you can do is probably to use a  
more recent x86 computer.
