Ue4 cave demo for linux

[RCL_]

That's what vogl, apitrace and friends are for

[xpander]

runs pretty bad indeed

but at least its something! cant wait to see it improved!

Check that the rar file has been correctly extracted. Ark didn't do it properly for me, had to use "rar -x" :P

For me it does not work, I get this log:

LogHAL:Error: appError called: Assertion failed: MaxComputeUniformComponents != -1 [File:Runtime/OpenGLDrv/Public\OpenGL4.h] [Line: 60]

That assert has been fixed in UE 4.2 and master (it could happen on GL3 NVidia hardware as well), but generally GL4 NVidia hardware and binary drivers are the only setup known to handle everything flawlessly so far.

Doesn't run for me, running with -pak I get the message "Using binned." and that's it.

Worked a charm, thanks.

In related news, my usually [still] excellent GTX580 sounded pretty asthmatic during some scenes. At 1920*1200 it was down to ~17fps This is the first engine that has truly stretched this card on Linux.

In the above demo, just pass "-pak" to avoid having to increase limits.

Why exactly do they want 10k open files, in a game. Epic, proper programming is calling, you might wanna take that.

We don't open upfront anymore and instead let them fail later. This is mostly needed for editor (and uncooked games), packaged game can start Ok without that. In the above demo, just pass "-pak" to avoid having to increase limits.

Haven't seen the specific error messages I see with latest mesa.

This particular error should be fixed with current git version of engine, but RCL said me on IRC that even latest version of engine don't work on Intel drivers yet (he didn't tested it with other drivers).

If you want join #ue4linux at irc.freenode.net. There is plenty of good guys as well as Epic employees and one of guys was nice and shared pre-compiled shootergame for me, unfortunately it's didn't worked with same errors.

Why "Runtime/OpenGLDrv/Public\OpenGL4.h"? Is OpenGL 3 stuff in OpenGL4.h?

Oh okay, the segfault is in the logging stuff:
