So, big thanks for all the hard work Wizz :toast:

@qubit CSM disabled - no idea what this means

CSM is basically legacy mode for how windows handles BIOS settings and hardware config instead of using UEFI

This one of the cases that are improved by 2.39.3, screenshot please

How is it improved? I noticed he also utilized an MSI tomahawk, I also use one, though on a different platform. I wonder if his BIOS is beta as well. Or MSI implementation is broken in the beta. Mine is enabled but on 2.39.3 still shown as disabled.

It's the previous beta BIOS version 1H3 that showed having Resiazble BAR support. I see there's a new Beta BIOS (1H5) available for download.

run msinfo32, look for "BIOS Mode", that shows "Legacy"?
ok I'm home now and yes it does show legacy.

I like the new wording on the driver support: nice and clear.

Thanks for your continuing efforts with this utility. :cool:

Awesome, thanks for testing everyone. Surprising how many people have resizable BAR enabled

good on my end too! I have had it enabled 70% of the time since launch day. it seems to give WoW an error after 2-3 hours of gameplay though (no overclocks when testing this just SAM on or off), no other games have that issue. So I disable it for WoW. I have it on now cause I got bored of WoW and uninstalled it, so it has been on 24/7 for awhile now with 0 issues in a wide variety of games.

My Z390 Aorus Pro got a BIOS that enables Resizable BAR but I didn't enable anything related in the BIOS.

hmmm it looks like RTX 2060 does support the PCIe resizable BAR capability, NVIDIA just isn't enabling it in the drivers. Will verify here tomorrow with a 2060

edit: confirmed, the 2060 reports back 3 BARs that can be resized

so I guess I'll add a check "if turing, set 'Resizable BAR enabled in BIOS' to 'GPU lacks Resizable BAR support'"
