Ratchet & Clank: Rift Apart PC Performance Review and Optimisation Guide
CPU Performance – Do you need a strong processor to play Rift Apart?
As a current-generation console exclusive, we expected Ratchet & Clank: Rift Apart to be CPU heavy, and we were surprised to learn that the game did not scale well with CPU core count. even with four CPU cores, we found that Rift Apart ran well on our i9-13900K based test system, signalling that the game is more single-thread limited than multi-thread limited.Â
We also tested our DDR5 memory at various speeds and found that the game did not respond much to DDR5 memory speed reductions, suggesting that the game is more limited by single-threaded compute than memory performance. With our RTX 4090, we did see GPU utilisation drop during many areas of our test scene, suggesting that the game is CPU/memory limited in some way. Â
When ray tracing is enabled, Ratchet & Clank: Rift Apart sees its average framerate drop significantly but its lower percentile framerate performance see a miniscule decrease. Again, the game is CPU-limited but appears to be more single-thread limited than multi-thread limited. Even when our CPU is reduced to four P-cores we see no performance decrease from our CPU’s full 24-core configuration.Â
