The recommended setting (SafeTextureCacheColorSamples = 512) is fine. I know that. Safe Texture Cache (SafeTextureCacheColorSamples = 0) was used only for benchmarking.
6xIR is not a very demanding setting. Any budget/mid-range GPU can handle 6xIR these days.
It looks much better than 3xIR or 4xIR at 1080p (super sharp + no aliasing) while being less demanding than using 3xIR plus any type of AA (MSAA or SSAA).
AA is a performance hog (especially Dolphin's incredibly slow Direct3D11 implementation of MSAA). OpenGL SSAA is also not a good option (one of the settings either doesn't improve the image quality that much or doesn't work properly while the other one is very slow or introduces nasty graphical glitches). Increasing the IR on the other hand is a much easier job for the GPU, free of issues and improves the image quality more than any other type of AA.
What about using IRs higher than 6x? The good news is that they DO NOT offer any improvement in image quality over 6xIR.
You can set Dolphin to render at 20xIR and it wll still look the same as 6xIR, but use loads of VRAM and perform like a slideshow.
All Dolphin needs now to improve the image quality even further is to replace the Bilinear filter with a Nearest Neighbor filter for 1xIR and a Lanczos downsampling filter for high IR settings.
6xIR + EFB->RAM + Safe TexCache is an optimal setting for a TexCache stress test / benchmark.
