Running Cyberpunk 2077 Phantom Liberty fully maxed, with path tracing in the dense streets of Dogtown, is one of the toughest tests a PC faces. Building for it means assembling a flagship machine where every part is chosen to feed a top-tier GPU at 4K.
Quick Answer
To run Phantom Liberty maxed at 4K with path tracing, build around an RTX 4080 or 4090-class GPU, a Ryzen 7 or Core i7, 32GB of fast RAM and a 2TB NVMe SSD, with frame generation enabled. Expect this flagship build to cost roughly R55,000 to R80,000 depending on the exact card.
Start With The GPU
Path tracing is the most demanding lighting mode in any game, so the graphics card is the foundation of the build and claims most of the budget. An RTX 4080 or 4090-class card with frame generation is what makes maxed 4K path tracing in Dogtown actually playable rather than a slideshow.
Build A Balanced Platform Around It
A flagship card needs support that will not hold it back: a Ryzen 7 or Core i7 to avoid CPU bottlenecks, 32GB of fast RAM, and a quality 850W power supply. Strong cooling keeps the system stable through long sessions in the expansion's busiest, most demanding areas.
Storage And The Right Display
With the expansion, Cyberpunk exceeds 100GB, so a 2TB NVMe SSD gives comfortable room. Crucially, pair the build with a 4K monitor, ideally with HDR, because there is no point running maxed 4K path tracing on a lower-resolution screen.
FAQ
What GPU runs Phantom Liberty maxed at 4K?
An RTX 4080 or 4090-class card with frame generation. Path tracing at 4K is extremely demanding, so a flagship card is required to keep it smooth.
Do I need a top-tier CPU as well?
Yes, a Ryzen 7 or Core i7. Dogtown's crowds lean on the CPU, and a strong one prevents bottlenecks that would hold back the flagship GPU.
How much storage should I plan for?
2TB NVMe is sensible. With the expansion the game tops 100GB, and the extra space leaves room for other demanding titles.
Pro Tip
Enable frame generation alongside upscaling for maxed path tracing; the two together are what turn an unplayable frame rate into a smooth experience in Dogtown's busiest streets.
