Question about GPU compatibility with Leopard and how to switch which screen a full screen app displays on.

4,1 Mac Pro currently has a Gt120 and an HD 4870. These are period-correct Apple-vended GPU’s.

I’ve recently installed Windows 7 to finally play the games I’ve always wanted to. I quit being interested in video games around 2007-2010 so Windows 7 is completely adequate for the games I enjoy.

Right now, Crysis (2007) runs excellently on the HD 4870 with Dx10. At near max settings, I pulled off mid 30’s-fps in the GPU and CPU benchmarks. Actual gameplay is pretty fluid and rarely has any dropped frames and I notice no tearing. Beyond that, the games I’ve downloaded for demonstration purposes have all played wonderfully. Splinter Cell Blacklist (2013), Need For Speed Most Wanted (2012), COD: MW3 (2011), and FarCry 3 (2012) all glide along adequately in near if not at max settings at up to 1600x900 resolution.

The games that I really enjoy right now are Splinter Cell (2002), Star Wars Battlefront (2004), Flatout 2 (2006) and all of these play at max settings perfectly smoothly under OS X. Splinter Cell and Battlefront run under Rosetta in Leopard, BTW, but never drop a frame at max resolution.

The other games I’m enjoying now are under Windows and include Star Wars: Shadows of the Empire and Star Wars: Rogue Squadron. These are from the DOS or Win95 days so no use going on about performance. It’s like running a calculator app on a mainframe.

I will be purchasing full versions of Crysis (2007), the Splinter Cell trilogy, probably every COD from COD4-MW3, a few Need for Speed titles, MS Flight Simulator X, maybe a few Battlefield games etc. but generally older titles.

All that said: if I want to get the most out of my current setup, I’ve read that the Geforce GTX 680 was offered by Apple and even supports DirectX 12. In a sticky thread here, somebody mentioned that the card supports 10.5 Leopard in “single resolution mode”. I’m not sure what this means and whether or not it is a plug-and-play affair with Leopard if I buy the Apple-specific version of the card.

Finally, when I run games in OS X Leopard they may open in my left or right display. I don’t always agree with where the app launches. Is there any way to adjust which display is used? I try Command-Tab to switch apps or trigger Exposé or whatever I can but the apps lock my displays and the only way I can do anything outside of the game is to quit it. This is, again, within 10.5 Leopard so does anybody remember any tricks?

Thanks all.

Means completely un-accelerated, fail-safe EFI mode.

NVIDIA Kepler GPUs are supported natively with 10.8.2, but back then there were drivers that you could download from eVGA and install to 10.7.5. Anything earlier is un-accelerated.

😅 well that covers that. I doubt I’d get anything better than the 4870 under Leopard unless the 5870 by some miracle has a way to support it. The only reason I’d want the 5870 is dual mDP and DirectX 11.

Update: 5870 only supports one monitor under 10.5.8. It does not allow ANY 3D at all (any 3D app will simply fail to launch) and no Quartz acceleration etc. Basically unusable. But golly it sure is quiet compared to the 4870 and kicks extra butt in all the Windows 7 games I have. It’s a different class from the 4870 by far.

My HD 5770 works on Leopard but this GPU is quite noisy compared to the RX 580.

Just struck me that I have seen posts about changing the thermal paste on GPUs and that this could be why the noisy fan is used a fair bit.

Does Leopard support full 3D and graphics accelerations? Multiple displays at high resolution? Quartz etc?

Being that in Gaming in Windows, I’d want to be sure that whatever card is compatible with Leopard is also compatible with Directx11.

I’ve been spoiled now playing Crysis on two displays at 2k resolution each… I’d hate to step down.

I have the Mac Edition:

It is fully accelerated but I don't know what you mean by 3D apps. I assume it must work for dual monitors but never tested as this version only has one DVI and a pair of display ports but I only have DVI and HDMI setups.

I only just found that the reference design had 2 DVI ports at the cost of a smaller air intake opening.

I mean can it execute games or other things that are 3D rendering, like CAD or something else with models.

Haven't used it for such but given that some Mac Pros came with this GPU, I upgraded to this GPU back then and hung on to it, I would expect that it would work with such software of that vintage.

Not actually used for such myself as said though.

AFAIK, ATI HD 5xxx GPUs are only accelerated after the 10.6.4 special build that was released with mid-2010 Mac Pros, first time that macOS had drivers for the TeraScale 2 Juniper and Cypress GPUs.

No QE/CI with Leopard at all.

I see. Might have been mixing stuff un and just not noticed but I used this for photography on 10.5.8 for several years.

Only just reinstalled Leopard recently and it does not run in the same slow way the RX 580 runs on El Capitan as an example. Not yet done anything major with it apart from just generally fooling about. Might have to try to run something a bit more tasking.

Do you have a link for those Kepler drivers for 10.7.5 ? Would be a problem solver for some folks with ancient apps.

Like I wrote, BACK THEN. eVGA removed it from the website more than 5 years ago. Now that eVGA does not work with NVIDIA or sell GPUs anymore, I doubt that they gonna ever try to find ten years old drivers…

Maybe someone saved it.
