iRacing + Pimax Dream Air: The 90FPS Driver Setting

What this covers

• What the SBoys3 driver setting actually does, and why it isn't part of most Pimax setup guides
• A 150% render resolution target held at a steady 90FPS rather than dropping resolution to protect frame rate
• Results tested back-to-back across four different iRacing tracks, not just one favourable circuit
• Where this setting is likely to help most, and where it won't rescue an otherwise CPU-bound system

The usual trade-off this setting is trying to avoid

The normal choice on Dream Air in iRacing is resolution versus frame rate — push render resolution up for clarity and you give up frames, or protect frame rate and the image gets softer. The driver setting covered in the video is aimed squarely at that trade-off: it's a change made outside iRacing itself, at the driver level, rather than another in-game slider.

Why four tracks, not one

A setting that only helps on a low-car-count oval isn't a setting worth recommending — so this was tested across four different iRacing tracks with different car counts and visual load, to see whether the frame rate held up consistently rather than just on a best-case track.

The exact steps to apply the setting, and the frame rate numbers per track, are walked through in the video above — worth watching in full if you're chasing headroom on Dream Air in iRacing specifically.
