Lab result
Demon's Souls is Stable on Kiln. It plays start to finish, and arena fights — where frames decide dodges — hold 60 fps at 1080p on the reference rig.
Boss runs, archstone travel, and Nexus loads all verified. Deaths in the lab were skill issues, not emulator issues.
Settings that held 60
1080p Performance preset, discrete GPU selected. Latria's crowded halls and Boletaria's fire stay locked.
First-run shader hitches appear in new areas, then clear. Judge the frame rate on the second pass, not the first.
DualSense over USB verified. See DualSense for the setup that the lab uses.
Boot it
Kiln is a PlayStation 5 emulator for Windows PC. Install it, install official firmware yourself, boot system software, add the game you own.
