(Deno) RTX Video Super Resolution (2 Pass)
DENO Custom Nodes vunknown. The DENO info button checks Comfy Registry and marks this node when an update is available. RTX Video Super Resolution (2 Pass): optional Denoise/Deblur same-size pass, then optional VSR/High Bitrate upscale pass, frame-by-frame in one node. Low RAM mode preallocates the output on CPU and avoids a full intermediate batch. Needs NVIDIA RTX VFX installed. 1. Close every ComfyUI window first. 2. Click this node's `How to install` button. 3. Follow the visual web install guide. 4. Download the ZIP from that guide page. 5. Open `ComfyUI\custom_nodes\deno-custom-nodes\tools`. 6. Move `install_rtx_vfx_bat.zip` into that `tools` folder. 7. Right-click the ZIP inside `tools`, choose `Extract All`, then open the extracted installer files. 8. Double-click `install_rtx_vfx.bat` from inside `tools`. 9. If it asks `Install RTX VFX here?`, type `Y` only when the shown Windows path is inside this ComfyUI app. If it looks wrong, type `N` and stop. 10. Wait for the green `INSTALL COMPLETE` message, then start ComfyUI again. Full install guide: https://deno2026.github.io/comfyui-deno-custom-nodes/rtx-vfx-install/
