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..

orignal kernel, but got a retro replay or an action replay set as default freezer cartridge.
after pressing F7 the programm loads.

so, basically PEBCAK then :) to make that work reliable, use -keybuf to put a F7 keypress into keyboard buffer after reset (and after a suitable timeout). the autostart mechanism doesnt know about cartridges, nor anything that isnt the original kernal.

that pretty much NOT explains why it's working at times.

srsly, it happens, then it not happens, .... not happens, happens.. and be sure i tried various things like waiting less, waiting more. yet still if i do it 10 times the same way it can work a random number 0..10.

ofcourse it's easy to blame the user for doing <<RANDOM>> thing wrong instead of finding a solution. guess my collegues can be happy that i am not such a type of coder..

apart from the fact that i don't want to check the compile script or have "compile with f7" and "compile without f7". blabla. welcome to the world of working around quirks because the reason is not to be found or wanted to be found.. ^^

the reason is that autostart uses specific timing constraints. it works sometimes and sometimes not because the timing you press F7 with is not always the same.

and if you dont want to use the solution that actually works... ok. dont blame the emulator for it though, thats just silly =P

ah yes, then it makes totally sense why the problem occurs at times with instant f7 pressing or waiting with pressing f7 for a longer time (>10 seconds that is).

and i must admit lame me doesn't know how vice detects when to switch off warp-mode after loading a file.

but honestly this too is offtopic as it was not about "non-existant" vice bugs but rather vice performance (tipps).

thanks again at soci and compyx for comprehensive informations.

If you are on Windows, note that VICE can trap all mouse clicks, so if you have something in the clipboard, and right click somewhere you will paste it into the keyboard buffer.. this can wreck havoc on Autostart, or not depending on when you click and what the emulator is doing etc makes it somewhat random.

Went through settings and disabled the render filter to none. Switched SID to 8580 Resid. This currently gave me a variable FPS value between 45 to 52 fps. Funny enough emulation speeed variied from 95% to 105% even with emulation speed to 100% normal.

Setting the render filter to "CRT" gave me something like 12fps to 20fps.

On x64 that is.

Does "double size" and "double scan" have much of an effect in VIC emulation?

x64sc is on 68% speed and 15fps..

Are you sure certainly that your CPU is not throttling? I can even run X64SC (Winvice 3) on a Z8700 based atom laptop with no slowdowns. (And that includes Resid on and double screen/pal emulation)

by far the most CPU is wasted in resid and CRT emulation - all the rest is pretty irrelevant. you shouldnt have that sort of performance problems in any case.

@algorithm: got a decent hint for me to check upon throttling and current cpu speeds and such? got such a feeling myself, but up to now my findings didn't bring up a proof for that..

in windows itself the energy settings are re-set to max power.

You can try using HW monitor and monitoring temperatures before you run Vice and during. This will show you the multipliers as well as temperatures of the CPU cores.

Usually during boot/reboot, there is more cpu activity. Leave it for a few minutes, run hwmonitor, monitor the multiplier/temperatures, then run vice. Indication of throttling is when the temperatures go up (and multipliers are at a high state) then multipliers reducing after.

For some users, turning off turboboost (set 99% under cpu max speed in power settings) can help (even at non-turbo, your CPU should still have (Just about) sufficient power to run x64sc at 50fps.
