ROB RUN FPS Drops With Mouse Movement: What to Check
Updated · RobrunCodex
If ROB RUN is smooth with the mouse still but stutters when you move it, lower the polling rate in your mouse software and repeat the same test. This targets a specific symptom; it is not a guaranteed fix for every FPS drop or connection problem.
Check what actually triggers the slowdown
Compare standing still, moving with the keyboard and turning the camera with the mouse in the same area. If performance is poor even without mouse movement, this narrow check may not address the cause. Record the starting polling-rate setting before changing it.
Lower polling rate, then repeat the comparison
Open your mouse manufacturer’s configuration app and find Polling Rate. Select a lower supported setting, apply it and return to the game. The setting belongs to the mouse software, not a guessed graphics menu.
Repeat the same still-versus-moving comparison. Keep the change if it helps; if it makes no useful difference, restore the previous setting before testing something else. There is no universal target rate or measured FPS gain promised here.
If the stutter continues
Try updating the graphics driver and turning off third-party overlays, checking the result after each change. If the issue persists, record your hardware, mouse model, tested settings and a short example for support. Note any error code separately: a connection failure needs its own checks.
Common questions
Which polling rate should I choose?
Choose a lower setting supported by your mouse and compare the result. The developer guidance does not specify one rate that works for every system.
Does this fix every kind of lag?
No. This check is for a slowdown tied to mouse movement. Poor performance while still, disconnections and loading errors can have different causes.
Should I change several settings together?
Test one change at a time and keep a note of the original value. Otherwise you cannot tell what helped or restore the previous setup reliably.
