Hi Ravenman,

Are you using Firestorm? That only allows 2X and 4X (dunno why). The Linden Lab SL Viewer allows my iMac (nVidia 680MX) to go all the way to 16X.

Really, Maddy? I can't log in right now to double check, but yesterday I had my Anti-aliasing set to 8X in Firestorm with no trouble. I think it goes higher even. Maybe it's a PC/Mac thing.

[Madelaine McMasters]

Ya, I logged in to see if the ratios might be limited by some other setting (like shadows or such) and I could never get it to allow more than 4X. SLV allowed 16 no matter what. We can both scratch our heads over the reasoning.

[RavenmanSkwer]

yes i am i am using firestorm on a fresh install any other viewers you suggest?

[RavenmanSkwer]

yea i am using firestorm on a fresh install any suggestion of what to do and what viewers to use

[Madelaine McMasters]

If you need 16x, use the official SL viewer.

[RavenmanSkwer]

ok i downloaded sl viewer the latest release and im not able to set it to x16 but funny thing i got an message saying display setting have been set to the recommended levels because you graphics card changed from ATI Radeon HD 6700' to 'ATI Radeon HD6700M

[Madelaine McMasters]

I imagine the 6700M is slower than the 6700, because it's a "mobile" variant of the chip. There is a file called "gpu_table.txt" which contains presets for various graphics cards. I don't know where you'd find that on a PC, but it's in the application bundle Resources folder on a Mac. There's a column for "class", which sets the default low/mid/high graphics setting on launch (you can override that later when you go to Preferences) and a column for OpenGL version support. I can't think of a reason you'd be prevented from going to 16x anti-aliasing by either of those columns, but you might try increasing the class number of your card by one and see what happens. Don't fiddle with that file unless you like risking the wrath of your computer ;-)

And if you do like taking risks, here's a link to another graphics answer offered up by Nyll Bergbahn a couple years ago (and so caveat emptor!). It contains a command line trick to prevent the viewer from interrogating your graphics card to determine default settings and highest OpenGL version compatibility. You might try that. Go to the following page and search for "noprobe". I don't know if that'll reveal "x16" or make things worse!

ETA: Ack, I had a brain cramp and forgot you're on a Mac Ravenman. That last -noprobe idea won't work there, or at least I don't know how to change that startup setting.

I have been reading but ignoring the comments between you and finally got curious enough to look in Firestorm's Preferences >>> Graphics >>> Hardware Settings. As I remembered, I can choose anti-aliasing settings up to 16x with no trouble. If you can't, Maddy, I suspect that it's a Mac issue.

[Madelaine McMasters]

Yep, you and I won't be reproducing each other's experiences, Rolig. I've no idea why Firestorm would restrict antialiasing, although long ago my old Macs would crash if you enabled 16x, every time.
