Strange FPS difference

1

I also found a problem, deprecated_to_upgrade\isometric_game this demo ,there are huge differences on different machines(the same code)

A Computer hardware configuration
IMac2019 CPU intel8500 Memory 40G GPU Intel UHD Graphics 630 + Radeon Pro 570X

B Computer hardware configuration
GTR6 CPU amd 5900HX Memory 32G GPU Integrated Graphics

Run deprecated_to_upgrade\isometric_game this demo(the same code), A had 60+FPS , B had 1200+FPS ，Why

A run other demo had 600+FPS, so A no limit 60FPS

Likely one has V-Sync turned on, the other not.

Please read Optimization and profiling | Manual | Castle Game Engine for various pointers how to interpret FPS values. It says

You will also need to turn off “vertical synchronization” of the GPU to achieve arbitrarily high FPS.
