what i usually do to check on this (it comes up a lot in speedrunning) is first bring up the “stats for nerds” on youtube to get the source framerate
then you know how much each , or . keypress will take you
sometimes i could press frame advance fucking 5 times at 30 FPS before seeing a new frame (that’s ~6 FPS depending on how you sample, i think)
as I’ve updated my document a fair bit since, so here are some interesting obscurer finds in no particular order
Serious Sam (Palm OS)
Robot Tank (Atari 8-bit)
Battletank (NES)
Airwolf (NES)
The Dark (ZX Spectrum)
Egoman (Windows Mobile)
Red Sector (Windows Mobile)
3D House of Death (Windows Mobile)
SimCity 64 (64DD, Game allows you to go into first person and explore your City and meet residents)
LEGO Exo Force: Sentai Showdown Battle Series (Browser Flash)
Bust Hillary 3D (DOS)
Kombat (DOS)
Warhammer 40,000: Dark Crusaders (DOS, Cancelled but the game was mostly finished and is playable)
The buildings are polygons with a shader slapped over them obviously (well a shader slapped over the camera), but I’m pretty sure everything else are sprites. Whatever, it’s a cool look
