NFS Carbon NX 0.1.0-beta.7

What's fixed

• Freezes and the Atmosphere fatal screen after a long session (about 90 minutes). The texture cache was never trimmed on the Switch: it grew by about 30 MiB per minute until the game ran out of memory, could no longer create threads (cutscenes froze) and the console eventually hung. Texture memory is now capped at 704 MiB; the least recently used textures are freed above it.
• A hiccup every 5 seconds. The statistics report stalled the renderer for 130-215 ms every 5 s. The detailed report now appears once a minute.
• Cutscene freeze after a long session (from beta.6): smaller host thread stacks, kept.

What's new

• FSR upscaling is the new default. The scene is drawn at 80% and upscaled with FSR. At the reference clocks a 15-minute session ran at a median of 40.8 FPS, with 95% of the time at 30 FPS or more (earlier sessions at 90% with plain scaling: median 32 and 38, different scenes, so not a strict comparison). For the old look, set present_effect = "bilinear" and carbon_gpu_render_scale = 90.
• Controller rumble is on.
• Quiet by default: only warnings are logged and the statistics are off, so less frame rate is lost (most noticeable at the race start). nfscarbon.report.toml is included for performance reports: copy it over nfscarbon.toml for one session, then send the logs.
• README: verified DLC table and steps to recover when the profile fails to load after DLC changes.

Needs

• Your own game files: a dump of your original disc. No game files are included, and none are modified.
• A CPU overclock: reference settings are CPU 1428 / GPU 768 / RAM 1600 MHz. Expect about 30 FPS or better, with dips in the densest city scenes.
• Launch with title override (hold R on the game) and a host memory budget of about 3.2 GB. A forwarder works with the 39-bit option (Sphaira works).

Install

Unzip nfscarbon-0.1.0-beta.7.zip to the SD card root and put your game files in switch/nfscarbon/game-data/. DLC packages go in switch/nfscarbon/dlc/.

Known issues

• Audio still stutters around the start of a race (CPU saturated); clean in most other places. Short black shadow flashes; achievements unconfirmed.
• A very large DLC set with leftover extracted folders crashed profile loading; see the README for the verified packs and the recovery steps.

If you hit a freeze or crash, please send your logs (see the README).
