Quick Answer

Fallout 4 is light, so a R40,000 build runs it maxed and modded with huge headroom. An RTX 4070 Ti Super with a Ryzen 7 7800X3D, 32GB DDR5 and a 2TB NVMe pushes 144+ fps at 1440p and runs the heaviest 4K texture mod lists -- and maxes every modern AAA title.

Fallout 4 is trivial at R40,000

The 2015 base game runs at well over 144 fps at 1440p on an RTX 4070 Ti Super. Fallout 4's engine is CPU-bound in dense areas like downtown Boston, so the Ryzen 7 7800X3D's cache is the standout -- it holds frame rates high where the engine usually dips. The point of R40,000 is mod headroom and 4K gaming, not the base game, which barely uses this hardware.

The heaviest mod lists, handled

A maxed Fallout 4 load order -- 4K texture packs, ENB lighting, settlement overhauls and gameplay mods -- runs above 60 fps even in downtown Boston on this build, where lesser PCs stutter badly. The 16GB VRAM and 2TB NVMe handle the enormous mod folder and slow modded saves. Cap the frame rate near 120 fps to avoid the engine's physics glitches at high values.

Built for everything else too

Beyond Fallout 4, this build maxes RDR2, Cyberpunk and other AAA titles at 1440p and runs many at 4K, so a modded Fallout 4 is the easiest thing it does. A 240-360mm AIO keeps the X3D cool, and a 27-32 inch 1440p 165Hz or 4K 144Hz monitor (around R6,000+) suits its broad capability.

FAQ

Does Fallout 4 need a R40,000 PC?

Not the base game -- it runs at 144+ fps at 1440p on far less. This tier is for the heaviest 4K mod lists and 4K gaming, with Fallout 4 running effortlessly alongside modern titles.

Why does Fallout 4 stutter in cities even on strong PCs?

Its engine is CPU-bound in dense areas like downtown Boston. The Ryzen 7 7800X3D's cache minimises those dips better than any non-X3D chip, keeping the city smooth.

Should I cap frame rate in Fallout 4?

Yes. The engine's physics tie to frame rate and misbehave above 120 fps. Cap it near 120 fps even on this powerful build to keep the game stable.

Pro Tip

For modded Fallout 4 on this build, the Ryzen 7 7800X3D tackles the CPU-bound Boston dips -- and remember to cap the frame rate near 120 fps to avoid engine physics glitches.
