Cool VL Viewer forum

Not exactly sure if this counts as a bug or not, however I upgraded from Cool VL Viewer (experimental) v1.26.9.15 to v1.26.9.16 and there is a significantly noticable performance hit.

for example with v1.26.9.15 (and prior) I'd do well within the 15-25fps range with ultra, advanced lighting, no shadows enabled, but when I upgraded to v1.26.9.16 I am lucky to get 5fps, usually hovers around 3. I tried a clean install, manually deleted the entire cache folder, i use the same exact preference settings as before, and I don't seem to be able to get any good performance out of the viewer with those settings.. so I can only assume something may have changed with the render code or related to cause this?

In addition, nothing has changed with the Sim or my surroundings either, tried a sim reboot, etc., and as for my computer, same drivers, same Nvidia settings, same everything.


Anyways, just wanted to point it out and wonder if anyone else out there too is experiencing a performance hit with the latest experimental version?

Not a bug, indeed... LL keeps changing the shaders and rendering code (thus why I think it was way too soon to declare v3.6-materials a "release" viewer: it's hardly a beta as far as I am concerned, and the reason why the materials renderer is still only in the experimental branch of the Cool VL Viewer).

Please, do the same kind of testing with LL's latest viewer (though, the currently available one is already "old" when compared to the latest changes included in the Cool VL Viewer) and report such issue on LL's JIRA.

yep yep, silly LL well, i can report that in the latest beta (also release) of LL's viewer my framerate/performance is normal, however in this latest version of Cool VL I had a significant drop compared to the materials experimental one from the week prior which was on par with LL's performance on my pc. With you applying the latest commits on a faster cycle than Linden Labs pushes new versions, I guess it's safe to assume that whatever happened with the latest commits to cause my framerate performance to take a hit may also occur when LL gets around to updating the beta viewer .

Well, here's hoping that whatever happened gets noticed and patched up ^.^
