Found this Site ran by Andrew Kieschnick. Has some optimizations that speed things up…

…..This is a more optimized version of kos-1.1.3/addons/libdcutils/matrix.s. mat_transform is 15% faster and mat_apply is 9% faster. Just replace the old matrix.s with this one and rebuild Download

……This patch fixes a problem with gldraw passing “bad” polygons to the ta. You can see the problem by taking manual control of the gltest example and moving the cubes toward the screen until things get “strange”. Apply the patch in kos-1.1.3/addons/libgl and rebuild. Download

……This patch adds store queue support to KOS 1.1.3. My testing shows writing to vram using the store queues is about 2.45 times faster than normal writes (76 mbyte/sec instead of 31 mbyte/sec). The patch changes vid_clear, vid_empty, and ta_txr_load to use the store queues, and provides functions sq_clr, sq_cpy, sq_set, sq_set16, and sq_set32. Apply this patch to your kos-1.1.3 tree and rebuild. Download
