S4 League FPS unlock

  • overrides shift fly, scythe uppercut, plasma sword jump attack speeds to something more consistent to 60fps behavior
  • allows fps and fov adjustment

Instructions

  • load with an asi loader eg. https://github.com/ThirteenAG/Ultimate-ASI-Loader, ie. put d3d9.dll, s4_league_fps_unlock.asi and s4_league_fps_unlock.json next to the game exe
  • max_framerate, field_of_view and sprint_field_of_view can be adjusted in s4_league_fps_unlock.json, setting max_framerate to 0 disables the frame limiter and lets the game go as fast as it can
    • game runs on rough milisecond precision, recommend keeping framerate below 300
  • framelimiter_full_busy_loop in s4_league_fps_unlock.json adjusts the built-in frame limiter's behavior when fps limit is non 0
    • it is set to false by default to not fully busy loop before the next frame
    • setting it to true might improve latency when the game is rendering faster than the frame limiter, at the cost of busy looping cpu power usage
  • framelimiter_busy_loop_buffer_100ns is a mixed approach of framelimiter_full_busy_loop, enforcing some busy loop right before the next frame
    • framelimiter_full_busy_loop has to be set to false for this to take effect
    • it is set to 15000 by default to not always busy loop but still try and secure cpu resources timely for the next frame
    • when the game is rendering faster than the frame limiter, setting it to 0 would reduce cpu power usage, but might introduce latency and frametime jitter when there are active background tasks

json.hpp is optained from https://github.com/nlohmann v3.11.3 release
