Why higher FPS makes wallhopping harder

The claim, and where it comes from

Cap your framerate at 60 before practising wallhops. Higher FPS makes wallhopping much harder.

This is not a community rumour or something we inferred. It appears in the description of Wall Hop Practice, the most-played wallhop trainer on Roblox — over 257 million visits, live since 2020, still updated in August 2026 — written by the developer who built it. The same note recommends turning on shift lock and mentions the alignment keys, comma and period, as a way to turn against walls.

We are flagging the source explicitly because the advice sounds wrong. Every instinct built from other games says more frames means more control. For this specific technique, the person with the most data on it says otherwise.

Why this is plausible

We want to be careful here, because there is a difference between reporting advice from a credible source and claiming to know the engine internals behind it. We can verify the first. The second we can only reason about.

What we can say is that a wallhop depends on a contact that is marginal by nature. You are catching a brief moment where the game registers your character as having landed on a wall, and converting it into a jump. Anything that changes how often the engine evaluates that contact, or how long your character spends within range of it per evaluation, changes how forgiving the technique feels. Physics stepping, contact resolution, and frame pacing all interact in ways that are not guaranteed to scale neutrally with framerate.

So: the mechanism we are not going to assert. The recommendation we are, because it comes from the developer of the category's flagship trainer and because it costs you nothing to test.

How to tell if this is your problem

The signature is specific and easy to recognise. Your wallhops used to work, you changed nothing about your technique, and now they are unreliable. Somewhere in between you got a new monitor, unlocked your framerate, upgraded a graphics card, or Roblox updated and reset your settings.

The test is quick. Cap to 60, run twenty single-catch attempts, and count. Then uncap, run twenty more, and count again. Twenty attempts is a small sample but the effect people report is not subtle — if it is your problem, you will see it.

• Open Roblox settings (Esc) while in a game
• Find the framerate cap setting and set it to 60
• Run 20 single-catch attempts and record how many succeeded
• Uncap, repeat, and compare the two counts

What else to check while you are in there

The settings menu is where two other common wallhop blockers live, so fix them in the same visit. Shift lock switch has to be enabled at the platform level before the in-game Shift toggle does anything — a surprising number of people toggle Shift, see nothing happen, and conclude the game does not support it.

Separately, test that held jump chains on flat ground. Hold space and watch for a continuous bounce. If your character jumps once and stops, that game runs a custom character script that overrides the default humanoid, and no amount of framerate tuning will make wall techniques behave as documented. Move to a different practice place.

Finally, if your framerate is unstable rather than merely high, that is worth fixing on its own terms. Consistent visual feedback on the catch is what lets you learn the timing at all, and a framerate that swings between 40 and 140 gives you a different-feeling technique every few seconds.
