But consider that if you get a more powerful card at the same price you don’t need as much upscaling or frame generation. FSR being sightly worse is irrelevant if you can run the game at native.
I’m on a 3080, and if I’m getting 40fps in a title at settings I’m happy with (which is ending up more common than I’d like), not even a 7900xtx is going to give me the 90fps I’d much prefer. And, lest you think I’m being vastly unfair, I’ll also say there are no nVidia cards that will do so either. And yes, this is entirely dependent on your resolution, but the ultrawide I’m quite fond of is essentially the same pixel count as 4k144, which is a lot of pixels to attempt to draw at once.
The only way to get there (at least until the 5090 shows up, I guess?) is to do some sort of upscaling. And, frankly, FSR is - subjectively - not ‘slightly worse’ but rather such a artifact-y mess (at least in games I’m playing) that I’d rather have 40fps than deal with how ugly it makes everything.
XESS is a lot better, and works fine on AMD cards, but until FSR gets a lot cleaner, or everything starts supporting XESS, DLSS is still the best game in town.
As for NVENC, you’re absolutely right, unless you’re using it for streaming, and have a hard cap on upper bitrates because you’re not Twitch royalty. I’ll admit that’s an edge case that most people don’t have, or even need to consider, but if you do need low-bitrate streaming, and don’t want to deal with x264 doing it in software, well, it’s NVENC or sub-par quality from AMF. I’m honestly surprised they haven’t invested time in fixing the one real use case that hardware encoding still has (real-time encoding of low bitrates), but I suppose someone somewhere has an excel sheet that shows that the market that cares about it is so small as to be of no value to spend time on.
The best rule of thumb I’ve ever heard regarding Debian Stable is that if the kernel in stable’s default repo fully supports ALL your hardware, and the software in stable’s default repos fully support your workflows, it’s fine.
If those are NOT true, then you probably don’t want to use Stable, because you’ll either end up fighting it via manually compiled and installed software, or you’ll venture into so many 3rd party repos for updated packages that updating it later becomes problematic and prone to making the whole system catch fire and burn down.
