[Python] Python keyboad input simulation fast

Is it possible to bump up the speed of keyboard inputs using a normal python script or do I have to switch to C# or Rust? The goal is to simluate movement in a game where it comes down to ms. Below is the output of a quick analysis of the planned time and the actual time python needed to simulate the movement:

planned_s actual_s action
0.03125 0.0616778 (key, w)
0.34375 0.8544916 (mouse, left)
0.59375 1.3620928 (key, space)
0.625 1.4259067 (mouse, left)
0.703125 1.5822482 (key, w)

The current script uses the python packages keyboard and mouse.

def press_action(action, down):
kind, key = action

if kind == "key":
if down:
keyboard.press(key)
else:
keyboard.release(key)

elif kind == "mouse":
if down:
mouse.press(button=key)
else:
mouse.release(button=key)


The DB stores sets of actions that are then passed to the replay_action_sequence. These look as follows:

{'actions': [['mouse', 'left'], ['key', 'space'], ['key', 'shift']], 'duration_ms': 15.625}, {'actions': [['key', 'space'], ['key', 'shift']], 'duration_ms': 109.375}, {'actions': [['key', 'shift']], 'duration_ms': 31.25}]
​

def replay_action_sequence(action_intervals):
held = set()
for step in action_intervals:
# turn each action-list into a tuple, then build set
current = { tuple(a) for a in step["actions"] }
dur_s = step["duration_ms"] / 1000.0

for a in held - current:
press_action(a, False)
for a in current - held:
press_action(a, True)

held = current
precise_sleep(dur_s)

for a in held:
press_action(a, False)

def precise_sleep(seconds: float):
"""Sleep for `seconds`, busy‐wait last 1ms for accuracy."""
if seconds <= 0:
return
if seconds > 0.002:
time.sleep(seconds - 0.001)
end = time.perf_counter() + seconds
while time.perf_counter() < end:
pass


Based on some research and input from ChatGPT I have inserted these lines:

try:
windll.winmm.timeBeginPeriod(1)
psutil.Process().nice(psutil.HIGH_PRIORITY_CLASS)
except Exception:
pass


But they don't seem to have much impact.

As is quite obvious from my question I am still a beginner and would have thus preferred to stick with python. If you say it is not feasible that way, however, I would switch to C# probably as I at least had some contact with that. The C# script or resulting .exe could still be called from python though, right?
