Command and Conquer lagging?

Anyone playing Command and Conquer and see any lag?

I’m playing the very first GDI one and it seems to be lagging or slowing down on the last mission. The map is a little larger and there’s some more units than usual.

Is there any way to confirm this is the issue and get it back up to speed? Using PSX Rearmed core.

Thanks! :3

Extra notes:

Mouse speed is normal. Music is normal. Scrolling normal. Unit moves a little slow, then stops for a split second then continues to move -> repeat.

I can load two different states from different missions, and it’s normal in one, and slow in the other as if it’s normal… there’s no ‘gradual decrease in performance’ to be noticed… it’s bizarre.

Can’t use Mednafen because it says I have write errors (?) so… yes. ;d

… never mind, seems AI got stuck and had like 20 Tanks stuck in a narrow choke point, 3 tanks trying to go inside their own base with 17 piled up trying to get out. LOL Probably all the “Go here” commands being spammed on those 20 tanks trying to path around the blockage.

Isn’t that still quite a limitation though? Or is that just being too CPU intensive for the iPhone 5S?
