Hi Ian,

I did test with: "setenv DECOUPLE_SWAPBUF y"

The results surprised me as I got significant fps increase:

Q3: 1260 frames 17.5 seconds 72.0 fps 4.0/13.9/30.0/4.5 ms

I was surprised as previously this did not seem to make any difference (as also reported by IRINIKUS). Maybe this was because I was using uppercase 'Y', I suspect, rather than lowercase 'y', so user error....

And yes is at: 1280x1024

Here is link to DALLAS DS1742 Replacement Thread: https://forums.irixnet.org/thread-3360.html
I believe that GlitchWorks (who also make replacement DALLAS DS1687 for Octane) also now has one as well.
I am always posting on this as it has been such a life saver for all my O350s and Fuel.

EDIT: rerun on Fuel (800MHz + V12) + Octane (2 x 600 + V12) with lowercase 'y' and got small improvements:
- FUEL
-- Q3: 1260 frames 49.9 seconds 25.3 fps 19.0/39.6/81.0/9.0 ms
-- Q2: 689 frames, 13.8 secondsL 50,0 fps
- OCTANE
-- Q3: 1260 frames 51.8 seconds 24.3 fps 19.0/41.1/78.0/9.3 ms

Cheers from Oz,
