WinVice 3.1 speed/performance on Ultrabooks?

Currently i am coding on an Asus UX32VD Ultrabook (which should have some like an Intel Core i7-3517U 1.9 GHz in it). As of WinVice3.1 using x64 with FastSid does not work correctly anymore. Visuals yes, but Sound sometimes totally goes south (no filters and such).

From the Vice people i was told to use ReSid as FastSid is not supported anymore.

Now my problems start: With using ReSid WinVice drops to like 24fps on my system. Using x64sc with Resid gives me like 8fps.

Looking at procmon it seems like one core is maxed out as CPU load never goes over 24% (the graphs show a different picture as none seems to be properly used).

My workhorse laptop at the office can run x64+resid nicely and properly, but okay it got way more power than my ultrabook will have.

Somehow i got the feeling that my system (Win10 Creators) is not really working properly anymore.

That's why i am asking here.. Any of you guys got a laptop compareable to mine and how's WinVice working on your system? Or what are the general performance reports for WinVice3.1?

Before i go into the ordeal of doing a complete re-install i would like to hear what other experience with WinVice currently. If it's problem on my side, or if it's just how well WinVice works on lower spec (sort of) laptops..

you can wait forever for "warp speed optimizations" because that will never happen. what will be optimized is accuracy of the emulation. no idea why you would prefer crappy emulation either =)

the difference you see might be because of the SID emulation settings, which have been changed to be more accurate too. (and I/O being busy is not connected to warp speed at all - except perhaps that more accurate emulation needs more CPU)

guess you dont need accurate CIA emulation or VIC timing for scrolling bitmaps and/or color cycling :)

anyone who prefers warp speed over accurate emulation certainly doesnt hit the limits. at all :)

oh come on, just fix the damn warpspeed instead of trolling about vice settings.

there is nothing to fix, except for emulation bugs.

I still can get 311% warp on my faster Pentium II-400 while running my recently released scroller part.

What I've noticed is that resampling is still active while in warp mode. This is sort of counter intuitive as one might think that the sound is off as there's nothing audible. Actually it isn't and it's eating cycles as usual, and much more since 3.x changed resampling defaults.

Turn off sound for real or tune back resampling to "fast". Then likely you'll get much better performance for testing stuff in warp.
