v0.10.7 — no more starting on the integrated GPU

NGX on hybrid machines: the game no longer starts on the integrated GPU

A reporter's 32-bit game failed with NVSDK_NGX_D3D12_Init -> 0xBAD00001 (FeatureNotSupported) through every version of this tool — until he opened Settings ▸ System ▸ Display ▸ Graphics, added the Feeder's host64\dlss5-feed-host64.exe and set it to High performance. It then worked on the first try (#25).

His laptop has an AMD Radeon adapter beside the RTX 4070. Windows had been starting the helper on the integrated GPU, and NGX does not exist there at all — so no install, driver or file layout could ever have fixed it.

Install now writes that preference itself, on any machine with a non-NVIDIA display adapter next to an NVIDIA one:

• GpuPreference=2; under HKCU\Software\Microsoft\DirectX\UserGpuPreferences, keyed by the executable's full path — exactly what the Settings app writes.
• For the game's exe, and on a 32-bit game also for host64\dlss5-feed-host64.exe.
• The value is a token list, so only the GpuPreference token is replaced: Auto HDR and a chosen adapter survive.
• Remove deletes the value again, but only while it is still exactly what was written — your own choice is never touched.

Also in this build:

• Diagnose names this cause when it sees 0xBAD00001 on a machine with more than one GPU vendor, and says whether the preference is already set.
• --check prints the machine's adapters and the current preference for that exe.

If you are on a laptop or a desktop with an integrated GPU and DLSS 5 never started, run Install once more from this version.
