I know Density altitude is pressure Alt corrected for non standard temp but for performance calculations is pressure Alt on its own of any use?

I've seen very few performance charts that actually use density altitude. Normally they'll use pressure altitude and then have the temperature as part of the calculation. So yes, it's useful.
