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) […]

A new screenshots comparator and loads of new x264 x265 vp8 vp9 tests

I bought the Blu-ray of “The Hobbit: An Unexpected Journey” (which is considered to be a reference for video quality) and I decided to do more codec tests. If you want to know something about my methodology please read my previous article. I ripped a scene from the Blu-ray and I cropped it to 1920×800, then […]

Who washed my video? x264 vs x265 ‘placebo’ comparison

I wanted to know something about the actual x265 development state and since I didn’t find anything up to date I decided to do my own tests. First of all I compiled a recent snapshot of x265:

./x265 –version x265 [info]: HEVC encoder version 0.7+259-5e2043f89aa1 x265 [info]: build info [Linux][GCC 4.8.2][64 bit] 8bpp x265 [info]: […]
