There is a small improvement from installing the drivers from Via over using built-in, however with only 10ms difference it could just be random variation from small sample size. (105ms audio lag is still way too much to be even close to acceptable, so I didn't bother taking more samples. It doesn't matter whether audio lag is 105 or 115 ms, so there is no point in taking more samples to find out. I'll keep doing 10 samples until audio lag on Dolphin / FM is < 50ms.)	Nvidia Control Panel settings: Scaling=display, vsync=off, Win10, i5-750, single monitor; Faster Melee video speed up settings / codes / hacks disabled in this build, left as supplied by Tino (dev)	XAudio2: Latency=0, Via integrated audio (Asus P55D-Evo) with v11.11 official drivers. No noticeable improvement from installing the drivers from Via. The new alpha Ishiiruka seems to improve audio lag slightly at best, with 9 ms less minimal lag (might just be from small sample size with this series, though). In any case, 106ms average audio lag is still way too much.	Nvidia Control Panel settings: Scaling=display, vsync=off, Win10, i7-2600K, multiple monitors (exclusive fullscreen on non-primary); D3D 11 in FM4.9 has a bugged aspect ratio on CRT monitors used as secondary monitors to primary LCD monitors	XAudio2: Latency=0, Asus Xonar DG with UniXonar drivers.All driver audio features disabled, sound set to "Hi-Fi" (seems to force-disable audio "enhancements"). Much more audio lag than integrated Via audio.											TV = Timing Variance setting in /user/config/dolphin.ini							30ms less audio lag than FM4.9	8 buffer: 4.6ms less video input lag than console+CRT		9 buffer: 0.5ms more video input lag than console+CRT. Compared to 8 buffer, we have 5.1ms input lag increase, which is slightly more than the theoretical 4.167 ms (due to small sample size probably). Still, it's accurate enough to see that even with FM5.5, the old recommendation still holds true: 9 buffers for 120hz CRT, 8 buffers for 120hz LCD, 7 buffers for 60hz CRT and 6 buffers for 60hz LCD.	Audio input lag is still massive. The Xonar DG is one of the slower cards, surprisingly, so with integrated audio or custom minimal audio buffers you should get up to 30-40ms less. Even then, you'll have 60-70ms sync delay over console, so I'd say the lag is still big enough that playing with completely mute audio is appropriate.			CPU load: ~30-78%, GPU 40-60%		Enabling "triple buffer" in Nvidia CP globally did not increase the input lag, but also did not remove tearing.
46	Testing procedure: I compared the button input that initiated an in-game full black to full white scene change (can be accomplished within develop mode) with the green line of the RGBHV video output and two photodiodes, one mounted at 25% from the top of the screen (120 Hz CRT monitor), and one mounted at 25% from the bottom. When only using one photodiode and no green video signal, tearing leads to sometimes getting measurements that are lower than justified (if the frame tears just a few lines above the lower photodiode's position, the player does not get to perceive this frame's relevant in-game cues in time). So whenever tearing happened between the two photodiodes, I kept counting until the next 120 Hz frame's lower photodiode activation. If a CRT was used, it's always a lagless computer monitor (Sony GDM-F520 [137khz] usually, sometimes Sun GDM-5510 [130khz]).																																							Idle power draw: 80W
