As per Zell's recommendation to post the results, the following's a test I ran using Derp's Episode 02 OP passage:

Intel i5 760 (2.8GHz, quad core, 8GB RAM), CCCP - no lag
Intel C2D E8400 (3.0GHz, dual core, 4GB RAM), CCCP - no lag

Intel C2D E6600 (2.4GHz, dual core, 4GB RAM), CCCP - LAG ( <-this PC used to handle everything that my laptop couldn't, including [Derp]_DenYuuDen OPs).

^ Same machine.........................................., CoreAVC - LAG (no lag apparent until towards the end of the OP, ~2:27 of episode 02)

AMD Turion 64 X2 TL-50 Mobile (1.6GHz, dual core, 2.6GB RAM), CoreAVC - LAAAAAAAAAAAAG

Conclusion: It takes a powerhouse to render those subs.

Note that the number of cores doesn't really matter as the decoding's single-threaded. The clock-speed and architecture (how new, and resultantly more efficient, the CPU is per clock) would play a bigger part. I don't think the i-series was that much more efficient than the C2Ds though.

Not true. Although I'm not altogether sure about CoreAVC as I haven't had it installed ever since I switched to this quad core. Or are you referring specifically to the subtitle rendering? If so, then I have no idea and you might indeed be correct.

You're right, my knowledge was (really) backdated, and H264 multithreaded decoding was emerging as early as 2007. :O

I confirmed in Media Player Classic's threads to see what's going on, and sure enough I see 4 threads (assumingly because it's a quad core) decoding comfortably. (<2%CPU per thread).



When the OP starts playing, the thread required for subtitle rendering jumps rockets up. It peaks at 20% CPU towards the end, at which the clock rate was 3.2GHz. Working out the load on a single core, turns out that the thread alone required 2.5GHz worth of calculations on the i5 at that point - which seems consistent with our previous results.(the 2.4Ghz struggled, then failed.)



In summary: H264 - multithread (thanks for the correction), easy. Subs - single thread, killer.

Work-around for if you want/need Derp (applies to ED too):

1) Skip the OP, or if you must watch it,
2) Turn off subs while watching OP (use the "s" key in MPC to cycle through the subtitle tracks.)


edit: DXVA isn't on animus. Perhaps that may be workaround #3

Well now that Derp's little puzzle's solved..

-----------------------

Although the mysteries were pretty easy to solve, I like the atmosphere that the anime provides.

The gun/lock trick was easy, but that was the only mystery I got. I couldn't see the room change, or the wallpaper (yes, the wallpaper!!) until it was shown to me. I always had a feeling I was never cut for detective work...
