What are people's general experiences with running new applications on old graphics cards? For example, how well can a 10-year-old GPU handle a modern Linux desktop or lightweight games? What kind of performance loss can be expected? What tweaks do you recommend for systems with hardware limitations? Let's keep this focused on open-source drivers and basic performance optimizations.
How do older GPUs handle modern software?

Comparing an aging NVIDIA GTX 660 (2012) to a GTX 1050 (2016) makes sense because architectural evolution directly translates to performance. For example, in Linux with open-source Nouveau drivers, the GTX 660 can only utilize 30-40% of the GPU—on top of just 1-2GB of VRAM. Meanwhile, the unofficial 390.x AMD drivers on the same system achieve 60-70% utilization, allowing even a decade-old card to run clean Xfce or LXQt desktop environments smoothly.
For older hardware, the most critical setting is disabling hardware-accelerated rendering. In Nouveau, your desktop environment choice matters: GNOME or KDE Plasma can push GPU load to 2-3 times that of Xfce. Similarly, even in lightweight games like OpenTTD or 0 A.D., running at Full HD can cost you 50-60% FPS, but dropping to 720p with low settings stabilizes performance at 30-40 FPS. Ultimately, both the age of the GPU and the availability of proper hardware-accelerated drivers define performance—take an AMD R7 250, for instance, where official Linux support makes even old games like Samsung’s Bellagio playable.
What do you struggle with the most when trying to run a new Linux desktop or light games on an old GPU? I think the most annoying things are screen tearing and freezes—do you experience the same?
