>Valve hasn't updated Reflex since it was added.
There's nothing to fix; it's not like DLSS where the model gets updated.
It's pacing the CPU load to prevent the GPU's render queue from being clogged; these don't need version updates.
The game encourages you to enable Reflex & G-Sync for the optimal experience.

NVIDIA and Valve got it right the first time, unlike Anti Lag 1 which got accounts banned.

Different chip architectures have different performance bottlenecks.
NVIDIA GPUs have more lower-level cache compared to Radeon chips in general; they are less reliant on rebar for that reason.

>Rebar
Different GPUs, different architectures, different performance bottlenecks.
Radeon GPU performance scaling better with REBAR-enabled just means these chips have a bigger memory bottleneck.

A GPU being more reliant on REBAR doesn't make it better. What matters is the final FPS.
