Slow graphics in Linux

[kasi]

Hi,

I recently discovered FreeOrion and gave it a try. Unfortunately, the game has unbearably slow graphics on my laptop. The laptop has an Intel I5, Intel HD 4400 graphics, an SSD, and runs Arch Linux (kernel 4.2.5-1-ARCH, xf86-intel 1:2.99.917+478+gdf72bc5-3).

I have already experimented to try and get it running. Here are some findings, but in short, it still doesn't work:

• Increasing "VideoRAM" for the intel driver in my xorg setup to 2GB improved the graphics throughput, and the mouse pointer is no longer lagging on the title screen; however, it's still lagging if I already open the 'Options' menu in the title screen.
• Changing DRI settings in the intel driver to use DRI 3 (instead DRI 2) didn't improve things.
• Using "glamor" in the intel driver, did not help.
• Reducing the FPS in the settings did not help
• Starting with the -r option or using just 16 color depth, did not help.
• Compiling with -O2 improved the performance, but overall did not help.
• Using a different kernel version (arch LTS: 4.1.15-1-lts), did not help.
• Compiling it from the git repo and the official tarball makes no difference.

Do I really need a stronger graphics card than an HD4400? From the forums, I see that people were playing the game 5-6 years ago, so it should be playable on a modern laptop, shouldn't it?

OpenGL is working:

Code: Select all

$ glxinfo | grep version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL core profile version string: 3.3 (Core Profile) Mesa 11.0.7
OpenGL core profile shading language version string: 3.30

OpenGL shading language version string: 1.30
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.0.7
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00

glxgears as a demo is working.

Staring freeorion with LIBGL_DEBUG=verbose shows that freeorion is loading the DRI library:

Code: Select all

libGL: pci id for fd 9: 8086:0a16, driver i965
libGL: OpenDriver: trying /usr/lib/xorg/modules/dri/tls/i965_dri.so
libGL: OpenDriver: trying /usr/lib/xorg/modules/dri/i965_dri.so
libGL: Using DRI3 for screen 0

Any ideas whether I'm doing something wrong? Btw. just clicking on the 'Options' menu item freezes the program for 5-8 seconds until the dialog shows up. (I unfortunately cannot test it under Windows on the laptop)

In the options menu, turn off galaxy gas, starfields, and detection range circles rendering.

The issue is probably not whether you have "modern" hardware, but how the linux drivers are implemented. If it's doing older OpenGL stuff in software, or is moving lots of data through main system RAM, then anything that fills much of the screen could be very slow to render...

Your laptop has higher specs than the Windows laptop I was using as my main device before I got my current Linux box a few months back, and I was able to run it succesfully under Windows on that (I used to play it on an old netbook but that was before the AI was actually doing anything so a bad comparison).

Unfortunately I'm a Linux newbie and am still learning the basic ropes of Kubuntu let alone Arch, but I suspect Geoff's right that it's a driver issue because while my Linux box is, technically, slightly better than your i5 it's only just and it runs fine for me.

It is, of course, something we'd want to try and solve if at all possible but sorting it basically needs the help of someone with that configuration trying various options and looking into the codebase, assuming that getting different/better drivers isn't an option (yet).

The '-r' option already turns off most of them. I tried turning off the remaining items as well, however, it doesn't make a difference. So what I get from your post is that FO is using 'old' OpenGL calls which may now be implemented in software only and thus the game is slow.

That's a pity...

[Geoff the Medio]

If you've turned off all the rendering options, and it's still getting problematically low frame rates at reasonable galaxy sizes, then it's a driver problem. Most of the rendering has been updated to use vertex arrays/buffers, so is reasonably fast as long as you've got decent fill rates / colour blending, and even before that, it wasn't overly slow with those options disabled.

I didn't expect the Intel driver on Linux to be that bad. The interesting thing is that the compile flag -O2 seems to produce faster code for FO than -O3.

Btw. I now also tried running FO in VirtualBox with 3D acceleration enabled, however, that doesn't work well, either.

It seems that I have to live without FO.

[coCoKNIght]

Your hardware is decent and imo should be able to run FO no problem on linux. I've run FO on linux on a ~2009 HP Mini which has a weak 1.6 atom processor and crappy integrated intel graphics. I've also run FO on linux on a 2011 iMac and it was running smoother than on OS X...
What version of FO have you compiled? Have you tried any binaries, for example from you package manager?

I once compiled the latest revision from git, and now also compiled the tag 0.4.5. Both have the problem. I tried running the debian binary, however, there are too many old dependencies (e.g., boost 0.58, which again has dependencies already outdated on arch linux).

FWIW, here's my output of glxinfo
