hello,
the only explanation i can find is that this Gem version was not compile with the good openGL header. but i'm not a specialist.
the idea of openGL is, to allow for runtime (as opposed to compile time) use of hardware acceleration. so the headers should(!) not matter at all.
after compiling the latest without performance gain i thought the same and found out that i did not have the nvidia devs which i downloaded and then recompiled gem - without success.
i also checked the lib /usr/lib/xorg/modules/extensions/libglx.so -> libglx.so.185.18.36 this is ok.
is there some other thing i could/need to check ?
do you have "libglew" installed? if so, does it help to uninstall it (or disable it with "--without-GLEW")?
do you have an old Gem lying around that is known to have had hw acceleration in these patches? does it still have? (e.g. can we rule out that the problem is due to some driver upgrade?)
