radeonsi vs Catalyst 3DMark wine benchmarks

If a big team like CD Projekt RED thinks that using a wrapper layer like eON by Virtual Prgramming is a suitable solution for a AAA game port like The Witcher 2, who am I to ditch wine (which performs even better than eON)? I might even speak about benchmarking a native linux 3DMark version [...]

A new linuxsystems overlay: wine-d3dstream

This overlay allows you to build latest git version of wine with the D3D command stream patches which create a separate command stream / worker thread for WineD3D. This work moves OpenGL calls into a seperate thread in order to improve performance up to 50~100% and in some cases making the games under Wine faster [...]

A new linuxsystems overlay: radeonsi

In my previous post someone asked about my radeonsi ebuilds, so I decided to create a new overlay. This overlay allows you to use Keith Packard’s xorg-server glamor-server branch and Tom Stellard’s si-spill-fixes-v4 llvm branch (rebased from time to time by me). You will have to use my x11-drivers/xf86-video-ati and x11-drivers/xf86-video-intel ebuilds because otherwise they [...]

Radeonsi is faster than Catalyst with Steam games

As I said in my previous post radeonsi is becoming faster than Catalyst in several scenarios. Some peoples on phoronix didn’t think it was actually possible and blamed “old games”. So I decided to benchmark Steam games, in particular Half-Life 2: Lost Coast, Team Fortress 2 and Portal. Unfortunately these are the only Steam games [...]

Radeonsi is awesome, beats Catalyst!

Edit: see also Radeonsi is faster than Catalyst with Steam games.

I did some benchmarks of my AMD Radeon HD 7950 using kernel 3.15-rc4 + PTE patches (VRAM page table entry compression) + hyperz (R600_DEBUG=hyperz). I’m also using libdrm git, xf86-video-ati git, llvm 3.5 git, mesa git (OpenGL core profile version string: 3.3 (Core Profile) [...]

[Gentoo] G45/GM45 h264 VA-API video decoding

On May 2011 Intel released G45/GM45 h264 VA-API in their g45-h264 branch. More then one year later they still didn’t merge it to master and no one touched that code in the meantime.

Fortunately if you tweak your system a bit that code is good enough to play a 1080p video with a generous bitrate, [...]

[Gentoo amd64] 32 bit graphic drivers from git without the multilib overlay

If you use Gentoo amd64 and the Intel/Radeon/Nouveau Open Source graphic drivers you already know the problem: x86_64 drivers from git (like media-libs/mesa-9999 from the x11 overlay) are bleeding edge and fast, while the 32 bit ones from app-emulation/emul-linux-x86 are outdated and slow. This is especially sad considering the most demanding games are the Windows [...]
