CRT emu driver - Switching noise - New Astro City
« on: May 21, 2018, 11:49:56 am »
Hi,

I've updated my graphic card from ATI 4890 to 7870XT.
I've re-installed everything and so far so good, everything is working fine (CRT emu driver 2.0 b13).
The only difference is the noise I now get when the screen switches from 640x480i to super resolution. With ATI 4790 card, there was no any noise.
https://www.youtube.com/watch?v=M0v0SWmRrrI (please increase your volume speaker to hear the noise)

Do you think it's a normal noise ?

It's hard to say. Multisync monitors have ralays that sound bad on mode switching. Is that a multisync monitor? The way the new card/drivers deal with sync signals upon mode switching may make the monitor act differently that it did before, that's all.
Important note: posts reporting GM issues without a log will be IGNORED.
Steps to create a log:
 - From command line, run: groovymame.exe -v romname >romname.txt
 - Attach resulting romname.txt file to your post, instead or pasting it.

I's a Nanao MS9 15-24kHz.
My computer is plugged to a JAMMAsd which only output 15kHz.
Thanks for your reply @Calamity.
