- QualityScaler 2026.4 - 7 September 2026
🚀 QualityScaler 2026.4 is here!A big one — under the hood and on the surface. Smarter hardware detection, a sharper (pun intended) AI pipeline, a redesigned file list, and a long list of rock-solid fixes for a smoother experience worldwide.🎮 Your GPU, recognized instantlyNo more guessing games. QualityScaler now automatically detects every GPU in your system — NVIDIA, AMD or Intel — and shows it by its real name (say hello to RTX 5060 Ti instead of "GPU 1").✅ VRAM auto-filled from your card's actual dedicated memory✅ Hardware encoder auto-selected to match your GPU (NVENC / AMF / QSV) — always the fastest path to export✅ Zero setup, zero manual VRAM math🧠 A smarter, cleaner AI pipeline🧵 Seamless tiling — a brand-new overlapping-tile engine with edge feathering means tiled/low-VRAM upscales no longer show visible seams between tiles✨ AI Sharpening (formerly "AI Blending") — completel…
