Title: Difference in CRT_EMUs??
Post by: B2K24 on July 26, 2022, 02:39:52 pm

Hi,

Can someone knowledgeable please explain the differences? More specifically the differences between 4XXX and 5XXX series?
Is there that much difference before I place an order?

Thanks for any help and assistance.

Hi, you have better support from 5xxx series.

I have had a much easier time using a more recent/powerful card and the Crimson flavor drivers.
Specifically a video card with both dvi (for the pc monitor) and vga (for the crt) outputs to be able to have two screens working at the same time throughout the install process.

The key is that whatever card you have that you are using the appropriate driver, be it the Catalyst ones or Crimson.

The 5000 series and newer cards allow EDID emulation. You want EDID emulation.

The drivers are newer and work better.

Keep in mind that video cards are manufactured for a certain Windows (DirectX) version:

- HD 4000 series -> Direct3D 10 -> Windows Vista
- HD 5000 series -> Direct3D 11 -> Windows 7 +

Basically anyone using Windows 7 or newer must use HD 5000 or newer. Using a HD 4000 on Windows 7 is possible but its support is let's say hacky and problematic.

In order to make their pre-HD 5000 series compatible with WDDM 1.0 (Vista), ATI stuck a compatiblity layer on top of their old Windows XP drivers. That's what you still have if you want to use an HD 4000 card on Windows 10.

HD 5000 were the first cards with native WDDM 1.0 support, rewritten from scratch.

In short (since Vista is pointless): use HD 4000 for Windows XP and 5000+ for anything newer.

Thank you so much!!!

I'm happy I ordered a HD 7450 now to go with a spare rig I had lying around.

would one of those problems be rendering dual screen games like punchout or arm wrestling? or vertical games? Im using an HD4xxx card in win7 x64 and havent figured out how to display punchout properly in an over under format that fits the screen. I also had a problem with some vertical shooter games running at 50% and in an interlaced super resolution, I fixed the shooters by creating an custom ini and changing the resolution for the problem games which took forever, but still cant figure out punchout. Could I have avoided all this trouble by just using a HD5xxx or newer card?
