Mesa 18.1 is out with the shader cache on for Intel

Posted by , | Views: 4,720

Open source drivers on Linux have advanced rather quickly and now we have another fresh release out with Mesa 18.1 which was released yesterday.

One of the major new features, is that the shader cache for Intel is now turned on by default, which should hopefully result in smoother performance for those of you gaming with an Intel GPU. Vulkan 1.1 support for the AMD RADV and Intel ANV drivers, plus various performance improvements and bug fixes.

Here's their other feature highlights:

  • OpenGL 3.1 with ARB_compatibility on nv50, nvc0, r600, radeonsi, softpipe, llvmpipe, svga
  • GL_ARB_bindless_texture on nvc0/maxwell+
  • GL_ARB_transform_feedback_overflow_query on nvc0
  • GL_EXT_semaphore on radeonsi
  • GL_EXT_semaphore_fd on radeonsi
  • GL_EXT_shader_framebuffer_fetch on i965 on desktop GL (GLES was already supported)
  • GL_EXT_shader_framebuffer_fetch_non_coherent on i965
  • GL_KHR_blend_equation_advanced on radeonsi

Usual notice: Since I have an NVIDIA GPU I don't follow Mesa too closely.

It seems the Padoka PPA is stuck at MESA 18.0. I hope Ubuntu 16.04 will still be supported a little but this is not sure as it's not the case anymore of the unstable Padoka PPA.

yes a recent game at a time when mesa is actually good vs games that were made when mesa was not so good totally proved wrong

codythedragondudepersonally for me i have experienced issues with three games under mesa

aragami (probably a unity problem but crashes every distro i have tried)

the last tinker city of colors (devs said it might be a unity texture issue)

mark of the ninja (broken off center display)


keep in mind that i don't buy a crap ton of games so i can't speak for all games

mesa is still not perfect for gaming on linux

it's getting better but theirs always going to be that one game that is just not working or devs can't get working due to a limitation of the driver

I think that the release of Rise of the TR proves you're wrong. With this game I saw more issues with nvidia driver than with Mesa. In fact, one of the most incredible things of the open source driver was that Feral committed a bug fix on the driver. This means that publishers don't have to wait for AMD or Nvidia to fix their drivers.

Well I think it does, as I was answering to his last statement: "it's getting better but theirs always going to be that one game that is just not working or devs can't get working due to a limitation of the driver"

Also, the count of "old" games that are unplayable with Mesa is near zero...

pete910All those work fine with mesa with AMD, Expecting intel's IGP to run them well is a little unfair. Lets be honest, Intel make good CPU's but plain suck at the graphics side of things.

There is currently one game that has issue for me with mesa (I have a fairly good library too) and that is Dying light !

It refuses to work with mesa on anything other than Ubuntu for some weird reason

It has been working for me since Mesa 17.3 (I ended the game months ago).

On my launch options I have this: MESA_GL_VERSION_OVERRIDE=4.5 MESA_GLSL_VERSION_OVERRIDE=450 %command%

Check if that helps you!

Don't work for those not on *buntu distros. But thanks for the suggestion

Well, I currently have Kubuntu 16.04 (with padoka ppa) and is working for me (I've updated my kernel up to 4.13 when I played it, but the problem was at Mesa level due to a non standard usage of the API -AFAIK-)

playable and playable without texture corruptions and other issues caused by running a game in a mesa environment are two very different things

So, what games are you experiencing texture corruptions in?

I don't understand what your goal is, to be honest. Yes, mesa used to be much worse than Nvidia, but at this point they are mostly caught up. The main field they've been slightly slower at has been vulkan, but that is quickly being fixed as well.

Maybe it's time for you to check out how mesa is today, and not how it was 2+ years ago?

What nox said, give us some examples. The games I usually play on my system doesn't have texture corruption, so it's difficult for me to answer something that I don't experiment.

I have been using Mesa with AMDGPU drivers for more than two years by now (R9 380 and R9 580), I experienced game crash or hangs (and most of the times was a game fault) but I don't recall having texture corruption.

Last game I was having that was Insugency/dying light and Day of infamy but ironically on the gtx1080. Was one of the reasons that finally made me jump back to AMD/Mesa
