 Description  « Hide
Viewer 1.20.5 drops frame rates to zero as soon as VBO and / or Basic Shaders are enabled. Performance is so bad, that I cannot even get a screen shot or system data to paste.

I have tried this on another system, (slower) which doesn't have windlight capabilities and it seems ok, but it has an integrated nvidia video.

The performance is totally degraded when both or either of these options are selected which is completely the reverse of previous viewers.

Utilizing these options in 1.20.4 gave an increase of about 50% in framerate. Also, 1.19.1.4 gives the same increase as expected.

When either option is enabled, FPS drop from 23fps to 1 or 0fps.
Currently using ATI 8.4 drivers
