What is the maximum number of units Pyrogenesis can handle in a large-scale battle?

Hi everyone!

I was wondering about something, but I couldn't find an answer on the forum, so I thought I'd ask here !

Games like the original Rome: Total War can display thousands of soldiers on the battlefield. How does 0 A.D. compare in terms of its technical capabilities ? More specifically, how many units (or buildings) can the Pyrogenesis engine theoretically handle? I'm not talking about hardware limitations or FPS, but rather the engine's own technical limits.

Thanks !

There is no limit per se. Just depends on your hardware. At some point you'll probably run out of VRAM.

Currently there is only one artificial limitation - silhouettes system. It stores occluders as 16-bits indices to save memory. So we can have at most 65k units with silhouettes enabled. Without it's limited only by hardware as @Stan` said. But the silhouettes system is very easy to improve to not have that limitation.
