Or have I already done that by setting |CFLAGS=-O -pipe in /etc/make.conf? From the XFree86 port patches, it appears: config/cf/FreeBSD.cf is the place. The current port turns off optimization by removing the -O2 and -O on DefaultGcc2i386Opt and OptimizedCDebugFlags, respectively. |> My hardware: |> - Matrox Millenium G450 32MB DDR 1x AGP |> - Asus A7M266 DDR MB |> - Athlon Thunderbird 1.2GHz | |Then you don't want to hear my setup: Oh, I definitely do! | - G400 16 MB RAM AGP | - Epox 8KTA3/+ PC133 SDRAM | - Duron 800 MHz | - 4.4-STABLE, X build out from ports. | |Why is my poorer setup performing better than yours? Good question! I'll compile with -O2 next. I turned optimization off because that's what the XFree86 port was doing (figured it'd be a safer first step), but that's not the default for the CVS tree apparently. |Have you tried tuxracer or gltron? In tuxracer I can't push more than |9-11 FPS on average. And the pusling part, it the same whether I run it |at 640x480 or 1600x1200. Not yet, but I will. Let me rebuild and dig around some more to see what I can tweak. Say, also I'm running with the XFree86 DRI mga.ko module, not the SourceForge DRI modules, and I didn't compile in the Matrox HAL library. I'd be interested in which DRI modules you are using, and whether you've got the HAL built into your server. Thanks for the reply!
