18.5.1 slower to change refresh?

[pigjes]

I just updated my emudriver from 16.2.1 to 18.5.1 (beta15), and now everytime the card has to change refresh it goes a lot slower to change than in 16.2.1.
What I mean is for example starting up arcade_osd or vmmaker takes about 5 times longer than on the older version.
Also starting a game on groovymame takes longer before they start.

If I switch back to the 16.2.1 , all is back snappy again.Tried on 2 computers with different AMD cards (7970 and 7750).

I see a lot (15 disabled and 1 enabled)  more "displays" with no monitor attached and disabled in vmmaker on 18.5.1 than in the older driver. Can I somehow remove the unused disabled adapters?

Is this normal behaviour if so, then no problem...maybe someone has an explanation.

thanks

I had some issues too and decided to get rid of anything graphicscard related via display driver uninstaller. Works better now but is still a bit slower...but could also be because of the new Vulcan driver which still fails to SwitchRes my PS1 Logo.

Still.. i have to stick with it because in game movies are finally scaled properly with Vulcan...

There was a Windows 10 update maybe 12-18months back that made switching resolutions 10x slower. Calamity acknowledged this at some point, but it's not something he can get around IIRC. Not sure if Win 7 was affected as well. It might be related to that, i guess?

I have two Win10 cabs, the first of which is connected to the net and to windows updates, which takes like 4-5 seconds to bring up a new resolution sometimes. The second cab, not on the net and so not updated and running an 18-month-old build of Win10, switches instantly. Same version of crt_emudriver on both - beta 10 of 16.2.1, i think?

Hah, that could be an explanation (thanks for the tip). I read that teknoparrot also had problems after 1803 windows10.
Tried an earlier build of win10, but same slow refresh time on 18.5.1 (even opening vmmaker).

Tried another videocard (rx460) and seems lot faster now..
