How to Make Games Run Better on an Older Laptop
Laptops fight a battle desktops never have to deal with: cramped cooling, power delivery capped by a small brick, and a CPU and GPU sharing the same tight thermal space. The good news is that most of the biggest gains cost nothing and take minutes to apply. Here’s exactly what to do, in order of impact.
1. Plug In and Switch to High Performance Mode
This is the single biggest free win available, and it’s shockingly easy to forget. Gaming on battery or the default Balanced power plan holds your CPU and GPU back deliberately to save power, and high-performance laptops can lose 30 to 50% of their FPS running on battery alone. Go to Settings, then System, then Power & Battery, and switch to a performance-oriented plan while plugged in. This single change alone can boost CPU and GPU clock speeds enough to deliver a real 10 to 15% performance gain in CPU-intensive games.
2. Force Your Dedicated GPU, Not the Integrated One
If your laptop has both integrated and dedicated graphics, it may default to the weaker integrated chip without you realizing it, cutting your frame rate significantly. In NVIDIA Control Panel, go to Manage 3D Settings, then Program Settings, select your game, and force it to use your dedicated GPU. Real-world testing has shown this single fix adding roughly 9 FPS on its own in demanding titles.

3. Address Thermal Throttling
If a game runs fine for the first 10 to 15 minutes and then noticeably slows down, that’s the classic sign of thermal throttling. Your CPU or GPU is overheating and automatically lowering its own clock speed to protect itself. Dust buildup and dried-out thermal paste are the usual culprits on laptops older than a year or two. Reapplying thermal paste can drop temperatures by 6 to 10°C on its own, and a laptop cooling pad with the laptop elevated can shave off another 5 to 10°C on the CPU. Combined, fixing thermal throttling has been measured to add 13 to 14% more performance in real gameplay testing.
4. Try Undervolting
This sounds intimidating, but it’s genuinely one of the most effective tweaks available. Undervolting slightly reduces the voltage sent to your CPU and GPU, which seems counterintuitive, but it often increases real-world performance because the hardware runs cooler and can sustain higher boost clocks for longer without hitting thermal limits. Tools like Intel XTU or ThrottleStop handle CPU undervolting, while MSI Afterburner works for most GPUs. Make small adjustments and stress-test with a demanding game afterward if you see freezing or crashes, dial the voltage back up slightly.
5. Check for BIOS and Driver Updates
Manufacturers occasionally push fixes that directly affect thermal behavior. One real example: a 2026 update for a popular gaming laptop line corrected a fan curve error that had been causing temperatures to run 9°C hotter than necessary. Keep your graphics drivers current too, since they often include game-specific optimizations.
6. Clean Up Background Bloatware
On a thermally limited laptop, every background process stealing CPU cycles is thermal headroom your game doesn’t get. The same CPU can sustain higher clock speeds when it isn’t simultaneously juggling Discord, browser extensions, and manufacturer software running in the background. Closing unnecessary startup programs has been measured to add a few extra FPS on its own, a small but genuinely free gain.

7. Lower In-Game Settings Last, Not First
Once you’ve handled power settings, GPU forcing, and thermals, in-game settings are where the largest single chunk of performance usually comes from. Lowering shadows, textures, and anti-aliasing to Medium, and enabling DLSS or FSR Quality mode where available, has been measured to add as much as 18 to 22% on its own in real testing.
It All Stacks
Here’s the encouraging part: these fixes aren’t competing with each other, they add up. In one real-world test on a laptop running Call of Duty: Warzone, a power plan switch added 11 FPS, forcing the dedicated GPU added 9 FPS, fixing thermal throttling added 13 FPS, adjusted in-game settings added 22 FPS, and cleaning up background bloatware added another 4 FPS. Combined, that’s a genuinely dramatic total improvement from changes that cost nothing.
When Stutter Persists
If you’ve worked through all of this and games still hitch or freeze unpredictably, the cause might not be thermal or power-related at all.

The Bottom Line
An older laptop isn’t automatically a lost cause for gaming. Power settings, forcing your dedicated GPU, and fixing thermal throttling cost nothing and deliver real, measurable gains, and they compound with smart in-game settings on top. Work through this list in order, and you’ll likely be surprised how much life is still left in hardware you already own.
FAQs
Why does my gaming laptop perform so much worse on battery?
Battery mode deliberately throttles your CPU and GPU to save power. High-performance laptops can lose 30 to 50% of their FPS running unplugged.
How do I know if my laptop is thermal throttling?
If a game runs fine initially and then noticeably slows down after 10 to 15 minutes, that’s the classic sign of thermal throttling.
Is undervolting safe for a laptop?
Yes, when done carefully. Small adjustments followed by stress-testing are the safe approach, and it can reduce heat while maintaining or improving performance.
Does closing background apps actually help on a laptop?
Yes, more than on a desktop. Background processes compete for the same limited thermal headroom your game needs to sustain higher clock speeds.
What should I fix first: thermals or in-game settings?
Thermals and power settings first, since they’re free and address the root cause. In-game settings deliver the biggest individual gain, but work best layered on top of a properly cooled system.
