Battlefield Open Beta: Keep Your AM5 Cool & Your FPS High
The Battlefield Open Beta is finally here, and if you’re packing an AM5 beast like the Ryzen 7 9800X3D, you might’ve noticed something: your CPU temps are running hotter than usual. That’s because this game actually uses all available cores. All of them. And while that’s great for performance, it can turn your CPU into a mini space heater during long matches.
The fix? Put AMD’s built-in tricks to work through your motherboard’s Extreme Tweaker menu, namely Precision Boost Overdrive (PBO) and Curve Optimiser. These let you maintain high performance while reducing unnecessary voltage, resulting in lower temperatures and fewer thermal throttles when the action gets intense. Most 9800X3Ds can comfortably handle a -30 all-core negative curve, trimming several degrees off your temps and helping maintain boost clocks in those 128-player chaos storms.
Quick Deploy: PBO + Curve Optimiser in Under 2 Minutes
1. Jump into BIOS
-
DEL or F2 during startup to enter BIOS.
2. Enable PBO in Extreme Tweaker
-
Go to:
Extreme Tweaker → Precision Boost Overdrive
3. Dial in Curve Optimiser
-
In the same menu, open Curve Optimiser.
-
Set to All Cores, choose Negative, and enter 30. Some CPU samples may be comfortable with a higher negative offset.
-
(If unstable, try -25 or -20 instead).
4. Save & Exit
-
Hit F10 to save and reboot.

Extra Intel: DLSS Quality Mode – The Stealth Buff You Didn’t Notice
Even streamers like Stodey didn’t realise they had DLSS Quality turned on during the reveal.
DLSS uses AI to render at a lower resolution and upscale the image, but in Battlefield’s Quality mode, it’s almost impossible to spot the difference visually. The benefit? A noticeable FPS boost that keeps the game feeling fluid without sacrificing fidelity.
Turn off the Hollywood Filters
-
Chromatic Aberration – Adds fake colour fringing to mimic a camera lens. It might make screenshots look “filmic,” but in-game it just makes edges fuzzy and can obscure distant enemies.
-
Vignette – Darkens the corners of the screen for drama. You’re not filming a moody indie movie — you need to see every pixel of the battlefield.
-
Film Grain – Simulates old film stock by adding noise over the image. Great for 80s war movies, terrible for spotting someone peeking over a ridge.
These post-processing effects all reduce image clarity, which is the opposite of what you want in a competitive shooter. Turning them off gives you a cleaner, sharper picture and makes it easier to spot enemies in chaotic firefights.
Bonus Loadout: RTX 5000-Series – Cooler, Quieter, Same FPS
Battlefield’s beta can have your GPU chewing through watts and pumping out heat, even when you’re not gaining extra frames for the trouble. If you’re rocking a 5000-series card like the ROG Astral OC RTX 5090 you may be able to drop temperatures further whilst not sacrificing performance.
-
Drop power by 70–170W without losing frames
A tuned voltage–frequency curve keeps performance within 1–3 FPS of stock or OC mode, even in heavy hitters like Cyberpunk 2077 and Monster Hunter Wilds.
Whether you’re chasing top-tier efficiency or want your rig to stop doubling as a space heater, undervolting is the smart play.
