Created attachment 134752 [details] my SecondLife viewer's "About" page... Hi! When I play SecondLife I get a quite good frame rate out of my RX550... ... until I enable "Advanced Lighting Model" (ALM) (because i hoped 2 c shadows at a decent frame rate with that new GPU (b4 i used the APU's HD7660D and fglrx, which produced about 5fps when ALM was enabled, but they looked good))... Somehow a lot of things just disappear now until i move the camera really close to them (and then it looks like ALM works fine, but it is a ridiculously small area... about as big as a chest...)... Sometimes I c the things flickering, when i move the camera back&forth in a distance, that is "too" high, but then they disappear again, when the camera stands still again (in a "too" high distance)... Furthermore my viewer seems to think, that my RX550 can only handle "low-mid" graphics quality, so that i have to override that manually to "mid-high"... Videobenchmark.net lists the RX550 as "high end"... https://www.videocardbenchmark.net/video_lookup.php?gpu=Radeon+RX+550&id=3761 so it should be able to present all the shadows (Firestorm only needs less than 1GiB of GPU memory, if i understand the "Preferences" dialog correctly)... in fact it should even b able to present them at a good frame rate... Is it possible to fix that? Thx. Bye Arne

in the output of glxinfo: what does OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.2.1 OpenGL version string: 3.0 Mesa 17.2.1 mean? does it mean, that my box does not support OpenGL 4.5? -arne
your box supports 4.5 in core profile, and 3.0 in compat profile - this is to be expected, as mesa does not implement compat-profile for > 3.0
on Phoronix someone said, he/she was able to use that ALM on Mesa without any big render errors... can it be, that Mesa does not play nicely with the RX550? -arne
mesa 17.3 on Mint 18.2 (from some so called PPA) works great on that same RX550... :) so i just have to wait, that it comes to Archlinux/Manjaro... :) *w00t* -arne
