Yesterday, PC Battlefield 4 owners also received an update. As well as having the same fixes as the platforms, it also contained CPU and GPU tweaks along with support for Mantle – read more about this here.
The following are the additional changes…
- The new Mantle renderer has been added in Battlefield 4. Most players can expect a performance increase by using this new low-level graphics API.
CPU/GPU performance and monitoring
- Tweaked and improved CPU multi-core utilization to try and avoid stuttering and low framerate due to stalls that happened on some CPU and OS configurations.
- Users can now configure and control themselves how many CPU cores should be used in the game with the new “Thread.MaxProcessorCount” settings in User.cfg.
- “Render.DrawScreenInfo 1” now also shows information about which CPU and GPU is in the system, how many GPUs & CPU cores are used and which renderer (DirectX 11 or Mantle) is active
- Added new “PerfOverlay.FrameFileLogEnable” command that records frame times on CPU & GPU and logs out to a .csv file
- AMD Catalyst driver 13.12 (or later) is now recommended instead of 13.9
- Enabled tile-based compute shader lighting optimization on Nvidia for improved GPU performance (already active on AMD GPUs)
- Improved performance with rendering and spotlights for all GPUs, primarily in in-door environments
