I can tell you how surprised I was to find out that index triangles were slower than triangle lists on the PSP due to (I conjecture) a broken vertex cache in the PSP graphics hardware (guessing it was rushed out with this bug). The huge challenge of clipping triangles on the PSP - they had to be clipped on the CPU. I loved working on the PSP and wished we could have done more PSP projects.

Despite the limitations, many games pulled off amazing graphics. Many in the thread compare it to the PS2, but that's unfair. Doing better than PS1 graphics in a handheld was quite an accomplishment back then. Interestingly, the quality of the assets in these games didn't have a chance to show on the 480x272 screen of the PSP. However, many games, including Bloodlines, Gran Turismo, both GTA's, just to name a few, look very close to PS2 when upscaled. So the work was very much put into these titles, and it shows, even after two decades.
