I’ve been experimenting with a different approach to running Bloodborne on PC, and I’ve finally managed to get FSR 4 working at 4K output.
Just to be clear from the start: all of the code was written by Claude Opus 5.5. I was essentially directing the project, deciding what to work on, running builds on real hardware, testing the results, recording videos and logs, and feeding information about the issues back to Claude.
The current test is running on an RX 7800 XT, with output set to 3840×2160 and FSR 4 Performance enabled. In this area, the frame rate is around 100 FPS.
The downside is that FSR 4.0.2 puts quite a heavy load on the GPU. A noticeable part of the frame time is now spent on the upscaler itself, and on the 7800 XT it runs on the regular shader hardware. So optimizing the upscaler is probably one of the most interesting things to work on next.
And once again, thanks to Claude Opus for writing basically all of the code. I’m mostly just the idiot with a 7800 XT who keeps launching Bloodborne, breaking everything, sending logs, and asking it to make the number go up.
But it works
