DLSS5 runs on a 3.3.5a client. User-confirmed, in the feeder's own status table: World of Warcraft 3.3.5a over DXVK, 4K on RTX 5080/5090.
TL;DR
Feeder + DXVK + 3.3.5a = neural rendering on a WotLK client. Confirmed by user report (issue #15), not dev-tested. Expect half framerate. dxvk.allowFse = False was the setting that mattered.
The setup that worked
32-bit Vulkan via DXVK path: ReShade 6.8 x86 as global Vulkan layer, default dxvk.conf, dxvk.allowFse = False. DLAA at native size plus the 32→64-bit hop costs roughly half the frame rate. Guild Wars Reforged confirmed the same way on a 4070.
Honest flags
User-reported, not dev-measured. Half framerate cost. DXVK-only route (no native Vulkan in old clients). HUD processed with scene. Still: first hard data point that neural rendering reaches private-server-era clients.
Why it matters here
Our DLSS5 roundup parked these tools for lack of a Warcraft hook. This is the hook: Reforged-style HD visuals plus neural rendering on the same 3.3.5a clients our scene runs. Watch for Faebright/Reforged players picking it up — visual mods plus DLSS is how old clients stop looking old.
