Problems with Core i5 iGPU

Are you talking about Mesa3D unsupporting DXT/S3TC compression?

Yes

(from your post some days ago)…

This is more of an issue with the tests/examples than with the engine itself. You can run TestSkyLoading which essentially creates a cubemap from 6 JPEG files, as long as you don’t use DXT compression in your app you should be fine.

There is a way enabling S3TC / DXT compression by installing libtxc_dxtn 1.0 and enabling it using driconf.

More info: http://dri.freedesktop.org/wiki/S3TC

libtxc_dxtn source: http://cgit.freedesktop.org/~mareko/libtxc_dxtn/

libtxc_dxtn precompiled debian packages: http://www.debian-multimedia.org/pool/main/libt/libtxc-dxtn/libtxc-dxtn.php

Warning! May be illegal to install in some countries due to patents

As http://people.freedesktop.org/~cbrill/libtxc_dxtn/ states my iGPU is not supported by libtxc_dxtn

Another implementation of DXT compression is libsquish, http://code.google.com/p/libsquish/ but this seems to be outdated

So what exactly is the issue? Why can’t you just not use DXT textures? Its a simple matter of converting them.

Then there’s no need to install all this illegal software or whatever.



jME uses DXT properly, it works everywhere where there is hardware support for them

The issue seems not to depend on S3TX / DXT compression.

No, my hardware supports DXT compression, but the default driver does not. Or does jME implement its own S3TC / DXT compression code?

BTW: since problems remain, it seems like my problem is not related to S3TC / DXT compression

All the tests you mentioned to be crashing or not working incorrectly use DXT textures it seems. I don’t think Mythruna does, however.

the other problem seems to be solved: http://hub.jmonkeyengine.org/groups/mythruna/forum/topic/mythruna-crashing-on-start-maybe-because-of-dxt-compression/?topic_page=2&num=15
