have a look at this page http://us.download.nvidia.com/XFree86/Linux-x86/1.0-9755/README/appendix-e.html Appendix E. OpenGL Environment Variable Settings Full scene antialiasing Antialiasing is a technique used to smooth the edges of objects in a scene to reduce the jagged "stairstep" effect that sometimes appears. Full-scene antialiasing is supported on GeForce or newer hardware. By setting the appropriate environment variable, you can enable full-scene antialiasing in any OpenGL application on these GPUs. Several antialiasing methods are available and you can select between them by setting the __GL_FSAA_MODE environment variable appropriately. Note that increasing the number of samples taken during FSAA rendering may decrease performance. The following tables describe the possible values for __GL_FSAA_MODE and the effects that they have on various NVIDIA GPUs. __GL_FSAA_MODE GeForce, GeForce2, Quadro, and Quadro2 Pro 0 FSAA disabled 1 FSAA disabled 2 FSAA disabled 3 1.5 x 1.5 Supersampling 4 2 x 2 Supersampling 5 FSAA disabled 6 FSAA disabled 7 FSAA disabled __GL_FSAA_MODE GeForce4 MX, GeForce4 4xx Go, Quadro4 380,550,580 XGL, and Quadro4 NVS 0 FSAA disabled 1 2x Bilinear Multisampling 2 2x Quincunx Multisampling 3 FSAA disabled 4 2 x 2 Supersampling 5 FSAA disabled 6 FSAA disabled 7 FSAA disabled __GL_FSAA_MODE GeForce3, Quadro DCC, GeForce4 Ti, GeForce4 4200 Go, and Quadro4 700,750,780,900,980 XGL 0 FSAA disabled 1 2x Bilinear Multisampling 2 2x Quincunx Multisampling 3 FSAA disabled 4 4x Bilinear Multisampling 5 4x Gaussian Multisampling 6 2x Bilinear Multisampling by 4x Supersampling 7 FSAA disabled __GL_FSAA_MODE GeForce FX, GeForce 6xxx, GeForce 7xxx, Quadro FX 0 FSAA disabled 1 2x Bilinear Multisampling 2 2x Quincunx Multisampling 3 FSAA disabled 4 4x Bilinear Multisampling 5 4x Gaussian Multisampling 6 2x Bilinear Multisampling by 4x Supersampling 7 4x Bilinear Multisampling by 4x Supersampling 8 4x Bilinear Multisampling by 2x Supersampling (available on GeForce FX and later GPUs; not available on Quadro GPUs) __GL_FSAA_MODE GeForce 8xxx, G8xGL 0 FSAA disabled 1 2x Bilinear Multisampling 2 FSAA disabled 3 FSAA disabled 4 4x Bilinear Multisampling 5 FSAA disabled 6 FSAA disabled 7 4x Bilinear Multisampling by 4x Supersampling 8 FSAA disabled 9 8x Bilinear Multisampling 10 8x 11 16x 12 16xQ 13 8x Bilinear Multisampling by 4x Supersampling Could you try setting that variable, recompiling and report back what you find? thanks, Mitchell Laks _______________________________________________ gtkglext-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkglext-list
