Cyberpunk 2077 Gets P-Core Only Mode for Intel CPUs: It’s a Stuttering Mess

CD Projekt Red has rolled out Patch 2.11 for Cyberpunk 2077 with many fixes and new features. A “P-core preferred” mode has been added for Intel’s hybrid core processors (Alder, Raptor, and Meteor Lake). As you can guess, it prioritizes the P-cores for the render thread rather than distributing it across to the E-cores. This should improve the performance as the latency-sensitive threads remain on the faster P-core cluster. Unfortunately, that’s not the case.

The game is a stuttering mess in the “P-core preferred” mode, dropping to single-digit figures and even crashing at times. At 1080p Ultra, the Core i9-13900K (with an RTX 4090) averages 201 FPS with 1% lows of 136.5 FPS. Enabling the P-core option reduces the average to 125 FPS and the 1% low to 11.5 FPS. This is kind of surprising, as manually disabling the E-cores works fine.

I suspect CDPR’s solution confuses the Windows Scheduler, causing inefficient work distribution. We’ll update this post as soon as the developers or NVIDIA release an update for this issue. The complete list of PC-specific, UI, and Visual changes can be found below:

Patch 2.11 for Cyberpunk 2077 and Phantom Liberty is being rolled out on PC, PlayStation 5 and Xbox Series X|S. In this update we focused on fixing the most common issues encountered by players, including Finisher animations, and added a little something for Rayfield enthusiasts!

UI

  • Added a Radioport category in Settings → Gameplay to customize Radioport behavior. Enable “Sync to Vehicle Radio” to keep the music playing after exiting a vehicle. With “Cycle Stations with Button Press”, effortlessly switch between radio stations by simply pressing the Radioport button without the need to open the Radio menu. Enable “Save Current Station” to have the Radioport resume playing the radio station upon loading a saved game.
  • The data window that appears when scanning will no longer default to the “Hacking” tab rather than “Data”. Instead, it will now remember which tab was open last.
  • Fixed an issue preventing players from changing cyberware at Ripperdocs and seeing the Cyberware Capacity bar.
  • Added a pop-up message for when it’s not possible to activate Sandevistan during holocalls.
  • Like the non-Iconic variants, Iconic quickhacks will no longer have the duration displayed in their descriptions.
  • Made small improvements to the appearance of Net sites.

Visual

  • Neon-lit rims for the Yaiba Kusanagi CT-3X will now light up properly.
  • Fixed shadows appearing on V’s torso when wearing tank tops.
  • Fixed dark shadows appearing on V’s hands when holding some weapons with Ray Tracing enabled.
  • The Devil and Judgment tarot cards will now be properly displayed on the end-game reward screen.

PC-specific

  • Added a Hybrid CPU Utilization setting, which can be found under Gameplay → Performance. It can be set either to “Auto” (lets the operating system automatically decide how to distribute threads among the cores) or “Prioritize P-Cores” (prioritizes performance cores). It is set to “Auto” by default.
  • Implemented a fix that improves performance, especially on AMD RX Vega GPUs.
