Is resize bar supported for nvidia cards at the moment?

Hey all,

I was wondering if the resize bar feature is supported. I opened LACT randomly and noticed that it said that the feature was disabled. I thought it was weird so I booted into my BIOS and confirmed that above 4G decoding was on and resize bar was set to auto (there is no explicit enable option) and they were.

I kept feeling like there was something off about the gaming performance i was seeing but couldn’t quite put my finger on it becuase everything else was set accordingly. Any way I can enable it or am I out of luck ot maybe a way to confirm that LACT is reporting incorrectly? I was quite excited to move back to Bazzite especially after their recent gdx variant announcement but this would likely be a deal breaker for me unfortunately :confused:

My GPU is an RTX 3080 Ti and CPU is a R9 5900x

I cannot turn that resizable bar feature on in my gigabyte desktop that I am currently using, nor the 4g decoding option which was on my z690 gigabyte master motherboard that broke, but my current older desktop, its bios doesn’t support either, but the 3D card works fine mostly without that support, I think it improves the 3D games a bit if you can turn it on under windows 11, but I don’t know about Linux, as I never seen the resizable bar feature show in NVidia config or NVidia settings app under Linux, so I don’t know if kde plasma or gnome versions support it at all, it might just be a windows feature of the NVidia 3D cards. The 3D gigabyte NVidia RTX 3070 master card supports it, but I have in the gigabyte G1.Assassin 2 (rev. 1.0) motherboard does not support the resizable bar feature at this time, as the F12w bios from Oct 30, 2013 does not include 4g decoding or resizable bar settings in the dual bios, that desktop is using ddr 3 memory, so even if I could turn it on, I am not sure it would improve the 3D cards gaming in that desktop, Additionally, it is equipped with an Intel i7 processor, which prevents overheating unlike the Intel i9 series that requires liquid cooling that I have in my newer Alienware r16 pc is a intel i9 processor, which has a liquid cooling based fan on it, but my older G1.Assassin 2 desktop fans are not liquid based at all, and that’s what I have bazzite Linux on at this time. the gigabyte G1.Assassin 2 desktop still works just fine for linux but again its been years since the last firmware update was released for it, so even thought the 3D card is a lot newer the resizeable bar feature may not work in this older desktop that I put it in, which is what seems to work fine with hdmi only with bazzite nvidia image plasma kde version of bazzite nvidia deck steam. the display port had a problem in sleep mode, when it waked up it got no signal problem with monitor, but the hdmi seems to wake and get a display again, so that problem I did fix with the 3D card that supports resizeable bar which again is set to no on my gigabyte desktop. otherwise I have no problem with it, I did once have a radeon 3D card amd based I think but it failured me years ago, since then I have sticked with nvidia and intel based hardware, as I never owned an amd processor I am not sure but if I remember some video games didn’t like it, from what I read online, I seen them in stores, but I been unsure about how, well it preforms compared to the intel processor, has it worked well for you?

as I don’t know if the linux nvidia drivers support it at all, hopefully someone else can answer this question for you, but as far as I can tell there is no information under linux in the nvidia settings app about the resizeable bar , its turned on in my alienware r16 pc but again that running on windows 11 still, as I don’t plan on switching my newer desktop to linux, I cannot answer that question fully.

hm thanks for your reply. yeah in my case I’m noticing games are a little more stuttery than usual even compared to other distros. I might go ahead and try a different distro and grab LACT to see if the same thing is being reported. Might just try regular Fedora not the atomic versions of it

The Ryzen processors have worked really well for me. I think it was the Ryzen 3000 and 5000 series that really started giving Intel a run for their money. I started with a Ryzen 5 3600x in 2020 that was my first ever PC build. Then later on I upgraded to a Ryzen 9 5900x and actually curently looking to get either a 5950x or 5900xt, for the extra 4 cores. Compiling shaders in Linux to play games really benefits from more cores as far as I can tell, and some of the work I do would benefit from more cores as well.

so did you pick that login name, because it was used in the Hackers movie that stared angelina jolie from 1995, just wondering jesus? anyway that’s a favorite movie, I rewatch sometimes, I own the hackers from 1995 on dvd disc at home. pretty sure they used that name in the movie, of course, it might also be your real name?

at one point, I was think about getting a pc with an The Ryzen processors in it but I never did yet, its good to hear that they improved, as I was not sure about the quality, since that old amd radeon I owned which was a 3D card, if I recall I switch it to an nvidia 3D card years ago, back when uru online myst type game was like new around that time, I was using it, and the fans on that 3D card failure me, anyway that’s what I recall about it, but nvidia 3D cards I think right now are better but the newer amd 3D cards might be good too, I read something online about a new bolt graphics 3d card that is coming out that might be better than nvidia 50 series current new line, but I don’t know if thats true or just web talk about it. I read its linux drivers are open source for that 3D card if that information helps. this below is it called an Zeus GPU which might be good with bazzite linux maybe?

haha it’s my real name, it’s almost never available so I was amused when i saw that it was xD

Also, I ended up fixing my issue, turns out that aside from enabling above 4G decoding and resize bar, I also needed to disable CSM (for me it was in the boot settings of my BIOS) I guess at some point I enabeld it without realizing?

I’m already on vanilla Fedora thinking it was just Bazzite lol I’ll see if I want to switch back or not, now I feel too lazy to reinstall Bazzite lol
