    console

    Hi,

    -opengl4 is not working for me either, I have an Nvidia GTX670 with blobs 337.25. Works well without -opengl4 flag though.

    How do I pull down the console? Do I have to add the mapping in a conf file for it? I want to enable Stat FPS.

    The demos work fine here using the default gl3 renderer. A bit slowly on my old GTS 450 (nvidia's blob version 334) and perfectly on a GTX 760 (driver 340.24). With -opengl4 the 450 produces a mostly black screen (something weird going on with the shaders, or maybe half a gig of vmem isn't enough?) and the 760 simply crashes. There are also weird differences in scene lighting between the two setups. I'd upgrade the driver on my work box, but it's so damn hot today I doubt I can be arsed...

    Same problem here, earlier ones were okay but not these new ones. Runs perfectly without the -opengl4 flag though.

    Nice, can't wait to try some out. But not until I reinstall my PC, because it's half-broken and I don't want to break it even more...

    I also hope someone builds Unreal Tournament 4 for Linux at some point before the official alpha. That would be nice.

    Yeap, they should be here:
    https://github.com/EpicGames
    (Of course, you need to subscribe to an UE4 license for $20 first...)

    Looks like the demo that I tried (Stylized Demo) is attempting to invoke tesselation-related functionality on my radeon 5400 using r600g (GL 3.3).

    [email protected]:~/Downloads/Stylized_Demo/Stylized Demo/Engine/Binaries/Linux$ ./Stylized
    Using binned.
    4.3.0-0+UE4 7038 3077 379 0
    Mesa: User error: GL_INVALID_ENUM in glGetIntegerv(pname=0x8e81)
    Mesa: User error: GL_INVALID_OPERATION in unsupported function called (unsupported extension or deprecated function?)
    Stylized: ../../src/glsl/ir_constant_expression.cpp:519: virtual ir_constant* ir_expression::constant_expression_value(hash_tabl e*): Assertion `op[0]->type->base_type == op[1]->type->base_type' failed.
    Aborted (core dumped)


    Looking up pname=0x8e81, I get:
    static const GLenum GL_MAX_TESS_CONTROL_TEXTURE_IMAGE_UNITS = 0x8E81;

    Guess it's not surprising that it crashed if it's attempting to use functionality that isn't yet implemented.

    I hope you use an open BIOS, and open CPU microcode, and hardware schematics, and open....
    Otherwise you'd be a hypocrite.

    Seriously though, Linux has a pretty good claim to being the best OS, period. Similarly the nvidia driver is the best GPU driver. Therefore I use them both.
    It would be nice if the nvidia driver was open source, but since there are so few people with the skills and desire to improve it, I don't think it's particularly important. The situation with radeon drivers shows that it's no panacea.
