| Test Area | Outcome | |-----------|---------| | | Succeeded only with admin rights and compatibility set to Windows XP (Service Pack 3) . The 16-bit installer stub initially failed; manual launch of Setup.exe with XP mode resolved. | | Launch & UI | Launched successfully. UI fonts rendered pixelated; interface too small on 1080p (no HiDPI scaling). Resizable dialog boxes misaligned. | | File Compatibility | Could not open .PSD files saved from Photoshop CC 2023+ if they contained Smart Objects, Artboards, or advanced layer comps. Saved files retained basic layers but dropped unsupported data silently. | | Performance | Extremely fast (>3000% over-saturated CPU usage for simple tasks). No multi-core optimization; single-thread only. GPU acceleration absent. | | Stability | Crashed twice: once when using the Type tool with Windows font cache conflict, once attempting to import a clipboard image >4K resolution. | | Peripheral Support | Modern Wacom tablets worked as generic pointing devices, but pressure sensitivity and tilt failed. Scanner TWAIN driver no longer compatible. |
