Fps drops with modern games
« on: July 23, 2021, 01:26:28 pm »
Hello everyone,

it is my first post on this forum and english is not my first language so please excuse my further grammar mistakes.
So here it goes: I have a PC with an AMD 4650 gpu connect to a CRT SONY Trintron TV using crtemudriver.
If I run Mame games everything works properly, the issue comes when I try to play 'modern games' on my TV.
If I play Outrun2 coast to coast (Pc version, not the emulated one) the frame drops to 30fps, but the weird thing is that if I run the same title on a Pc monitor, on the same machine the frame goes back to 60 and everything is smooth and delicious.(Tried different resolutions, same results)
Same thing happens with Sonic Mania or Devil Engine, just to give you guys some other titles.
I think it could be a directx related issue.Does anyone have the same issue or could give me any advice how to fix that?
Thanks!

There used to be a problem with crt_emudriver where games using interlaced modes would run at half speed . I'm not sure if it's been fixed or not.

This is a thread about the issue: http://forum.arcadecontrols.com/index.php?topic=154706.0

I would post up about crt_emudriver problems in the GroovMAME subforum, you might get a better answer there.
