Hello all,

I'm quite new on PD and GEM and I'm having some trouble with performance. Especially if any other window (for example a PD patch) is overlapping the GEM window the rendering slows down considerably but also whenever I use bumpmapping or similar math intense operations and also pix_write.

I've been tweaking the hardware settings for the nVidia OpenGL rendering (using nVHardPage as the latest nVidia drivers don't have any OpenGL settings) and experimented with setting various parameters such as anti-aliasing and filtering, but there is no change in neither visual results or performance. Therefor I suspect that GEM doesn't utilize hardware acceleration. What do you think, can this be the case? Is hardware rendering switchable somehow?

I run PD/GEM under WinXP on a AMD 2600+/512MB with nForce2 integrated graphics and I've got a fast hard drive. I've googled and searched the PD-list without finding anything related. As far as I've noticed, I don't have any performance issues with graphics using other software or windows in general.

Very thankful for any help!
