I’ve been trying to make webcam QR code detection with BoofCV. I use the [DetectQrCode](https://github.com/lessthanoptimal/BoofProcessing/blob/master/examples/DetectQrCode/DetectQrCode.pde) example from BoofCV repository. For my application I need it to work at 60fps (with resizing the image from 640\*480 to 1440x1080), which is impossible without using P2D or P3D.  
With the stock renderer, I get about 40fps and QR codes are detected.  
With P2D or P3D renderer, I get steady 60fps, but QR codes are not detected anymore.  
Is there any way to solve that?

Solved this by using FX2D instead of P2D. With FX2D I get 60fps and QR codes are detected.
