RDR2 freezes at 3fps / 0fps after loading screen on PS5 Linux (Bazzite) — VRAM issue?
SOLVED! It was the wrong GPU adapter in RDR2. It now runs at 60fps on Ultra settings.
Hey everyone,
I'm running Bazzite on a PS5 Phat (FW 4.03) installed on the internal M.2. CPU/GPU boost is active (3.5GHz / 2.23GHz via ps5_control).
Issue:
Red Dead Redemption 2 runs at 30–40fps in the main menu, but as soon as the loading screen finishes and the game starts, it drops to 3fps and eventually freezes completely at 0fps. The game becomes unresponsive and has to be force-closed.
My setup:
- PS5 Phat, FW 4.03
- Bazzite (latest ps5-linux-image)
- ps5_control --boost on / --fan on (via systemd)
- Proton Experimental
- Launched via Rockstar Launcher through Steam
- VRAM usage: relatively low number shown in RDR2 graphics settings (exact value TBD)
What I've tried:
- Proton Experimental (current)
- Reduced graphics settings in menu
I've read that PS5 Linux currently caps VRAM allocation at around 6GB due to how Linux handles the unified memory pool differently from the native PS5 OS. Could this be causing RDR2 to overflow VRAM mid-load and crash?
Questions:
- Has anyone gotten RDR2 running stable on PS5 Linux?
- Is there a workaround for the VRAM cap?
- Should I switch to GE-Proton instead of Experimental?
- Any specific launch options that helped?
Thanks in advance guys!
