21 Ways to Improve Gaming Performance on Your Laptop

A friend messaged me confused because his “gaming laptop” with a dedicated RTX card was getting worse frame rates than his desktop with a weaker GPU, in the same game, at the same settings. We pulled up the on-screen GPU utilization overlay while he played and the dedicated GPU was sitting at 40-50% usage the whole time — nowhere near maxed out, which meant something else was the actual bottleneck. Task Manager showed the answer: the game was running through the laptop’s integrated graphics the entire time, with the RTX card doing almost nothing. He’d never touched a MUX switch setting in his life and didn’t know his laptop even had one.

That single setting turned out to be worth more than every other tweak in this list combined, so it goes first.

Force the Dedicated GPU With the MUX Switch (Worth Far More Than It Sounds)

Most gaming laptops route the GPU output through Nvidia Optimus by default, which lets the integrated graphics handle simple tasks to save battery and only hands frames to the dedicated GPU when needed — except that handoff isn’t free, and it can bottleneck the dedicated GPU’s actual output. Independent testing across a range of laptops has measured Optimus off (MUX switch forcing the dedicated GPU directly to the display) delivering anywhere from 10% to 25% more FPS, with one review measuring a 17% average across nine different games and another hitting a 25% uplift on an XMG Neo 15. The gain is biggest in esports titles running at high frame rates, where the iGPU handoff becomes the limiting factor rather than the GPU itself.

Check your laptop’s control software — Armoury Crate, Omen Gaming Hub, MSI Center, Legion Toolkit — for a “MUX Switch,” “Discrete GPU,” or “Advanced Optimus” toggle. Older MUX implementations need a restart to switch modes; Advanced Optimus, found on newer laptops, switches on the fly. The tradeoff is battery life while plugged in doesn’t matter, but if you’re gaming unplugged, forcing the dedicated GPU on will drain the battery noticeably faster — so this is a “plugged in” setting, not an always-on one.

Power Plan: the Gain Is in Smoothness, Not Average FPS

Switching from Windows’ Balanced power plan to High Performance or Ultimate Performance barely moves your average FPS number — testing shows it’s typically a 0-2 FPS difference, since modern CPUs ramp from idle to full boost in under a millisecond regardless of plan. Where it actually matters is your 1% low framerate, the metric that determines how smooth a game feels rather than what number shows in the corner — Balanced mode’s constant ramping up and down between clock states introduces frame-time spikes that a fixed high-performance state avoids, and that gap has been measured at 5-15% in 1% lows specifically. The laptop-specific catch: forcing max performance on a thin, hot chassis can push it into thermal throttling during long sessions, which cancels the benefit. Test it during your actual play sessions, not just a five-minute benchmark, before assuming it’s a free win.

Dual-Channel RAM Matters More on a Laptop Than You’d Guess

If your laptop shipped with a single RAM stick — common on budget and even some mid-range gaming laptops to hit a price point — you’re leaving real performance on the table, and it’s worse than the desktop numbers suggest. Benchmarks comparing single- to dual-channel configurations show swings from around 5% in lighter titles up to 20%+ in more demanding ones, and the gap is largest specifically at Low and Medium settings, where the CPU (and by extension memory bandwidth) becomes the bottleneck instead of the GPU — exactly the settings a budget gaming laptop owner is likely to be running. The effect shows up most in 1% lows and minimum frame rates rather than the average, meaning stutter during busy scenes rather than a lower number overall. If your laptop has a spare SO-DIMM slot, adding a second matched stick is one of the higher-value laptop upgrades that exists, often costing less than a mid-range game.

The Other Quick Wins Worth Doing

Once the three fixes above are handled, the remaining gains are smaller individually but still add up: set your Nvidia/AMD driver’s global power setting to “Prefer Maximum Performance” instead of “Optimal Power” (Nvidia Control Panel > Manage 3D Settings); disable Windows Game Bar’s background recording if you don’t use it, since it keeps a capture buffer running even when idle; close browser tabs running background video or WebGL rather than just minimizing them, since Chrome and Edge keep GPU processes active per-tab; update your GPU driver directly from Nvidia or AMD rather than relying on the laptop vendor’s bundled utility, which often lags behind by months; disable Xbox Game Bar’s overlay if you’re not using its features; set your laptop’s fan/thermal profile to “Performance” or “Turbo” mode in the vendor app before long sessions, not after you’ve already noticed throttling; and check that Windows hasn’t silently reset your GPU to the integrated option under Settings > Display > Graphics for that specific game’s executable, which happens more often than it should after Windows updates.

FAQ

Will using the MUX switch hurt my battery life?

Only while unplugged. Forcing the dedicated GPU on removes Optimus’s power-saving handoff, so it’s meant to be used plugged in. Most laptops let you switch back for battery-conscious use away from a desk.

Is High Performance power mode always better for gaming on a laptop?

Not always — it improves frame-time consistency but can push a thin, hot chassis into thermal throttling during long sessions, which erases the gain. Test your actual play sessions rather than assuming it’s a universal win.

How do I check if my laptop is running single-channel or dual-channel RAM?

Open Task Manager, go to the Performance tab, click Memory, and look at the slots-used indicator, or run the free CPU-Z utility, which shows channel configuration directly under its Memory tab.

Why is my dedicated GPU showing low usage even in demanding games?

This is the classic symptom of the game running through Optimus/the integrated GPU instead of the dedicated one. Check your laptop’s Graphics settings (Windows Settings > Display > Graphics) and set the specific game’s executable to use the “High performance” GPU explicitly.
