If you are talking about the integrated intel graphics on notebooks then there is only this official tweak panel available I think. But it has no noticeable impact in my opinion...
As far as I know there is no external program like RadeonPro for Intel graphics :/

don't think such a thing exists. sorry bud

If you mean trying to make your game look like this

then put this into your custom folder. This mod works on sv_pure.

you mean does NOT work on svpure

Is there a way to make your game look somewhat similar to post #4 or at least smooth the background out more? Would be a huge help for colorblindness

It looks to me that all you'd need to emulate the "smooth" textures would be to force the game to render using vertex shading. However, modifying a game's shaders/rendering pipeline also sounds suspiciously like a cheat.

no, i mean like what stabby uses

"mat_filterlightmaps 0" AND "mat_filtertextures 0" will make the textures look pixelated,
"mat_filterlightmaps 1" AND "mat_filtertextures 1" will make the textures look blurry (not as much as in the #4 post, because the texture resolution is too high)! Just change these settings in your cfg and try it :]

assuming he uses a nvidia graphics card, he uses nvidia inspector for a low picmip hack that works on sv_pure

although, it is banned in ESEA, here http://etf2l.org/forum/customise/topic-17728/

(thread might be a little outdated, but i hope it works for you)
