Preset CRT-SUPER xBR shader - low performance on 1.6.0

Hello, I recently updated to new RA 1.6.0 and wanted to use my favourite preset of CRT-Super xBR.cg, as there is not preset of this in glsl shaders. It’s weird but performance on Desmume core is laggy, where it always have been buttersmooth on older versions of RA and desmume core…

My specs: Pentium G3460 @ 3.5ghz GTX 750Ti 2gb GDDR5 4GB RAM ddr3

Cpu is quite slow but then again shaders use GPU power if I remember correclty. Is there any specific graphic option that I should check/uncheck to make my gameplay smooth? OR maybe some newer/ better preset for combning super xbr with crt on glsl language? Other cores works with no lag at all on this preset.
