Due to this difference of latency there may be unaviodable clicks in games (sorry, no concrete example) that frequently switch from 3 to 4 buffers and back. The FIR-based approach eliminates this effect, because there is no latency difference (or, because this is untested, better say: it's a bug in my code if there is any latency difference).
If your CPU is fast enough to play GTA:SA with full-quality resampler (I can't test because I don't have this game), you can test this clicking problem by setting the HQBuffersMax registry entry to something that is higher than the "normal" number of the concurrent buffers but lower than the peak number. When the threshold is crossed, something interesting (I guess, a click) should happen with the sound, and I also want to know what exactly :)
