Hello, does anyone have experience with how Intel's open-source driver performs for gaming with Valve's Proton? It's very hard to find benchmarks online, and the ones I saw showed a significant difference between gaming on Windows and Linux. I'm about to buy a new GPU and am waiting for RDNA4 to make my decision, but I might give Intel a chance given their pricing.

Depends how well their xe driver performs under BM. On Alchemist the performance is mediocre. i915 works well enough, ANV is slow in many games though.

Performance with my short time A770 was a total shit show in Linux on old systems without ReBAR / SAM (even with above 4G decoding enabled). Windows performance was actually much better at the time. My impression was basically...- Windows: you really should have ReBAR enabled
- Linux: you absolutely need ReBAR enabled
I was hoping there would be memory controller upgrades to make these usable for gaming in old systems.

So IIRC PCIE5 x16 64 GB/s; x8 = 32 GB/s; x4 = 16 GB/s.
All of those are WAY less than what one would hope one's RAM BW would be on a modern DDR5 PC,
and WAY WAY less than what one's VRAM BW must be. So right from the start even PCIE x16
is a bottleneck transferring between RAM / VRAM and CPU cache / VRAM relative to what the CPU and RAM and GPU should be capable of.
Then consider many PCs will have one or more GPUs loaded in slots that are only functional at x8 or x4 width in which case the 2x bps/lane improvement of PCIE-5 vs PCIE-4 makes the
difference between "horrible" and "bad but could be worse" GPU-to-system BW so it can
be a "win" there to compensate for a poor motherboard / CPU with less usable slot lanes than ideal.
And as others said faster rate can improve latency of transactions so it aids in responsiveness / transactional throughput as well as "hurry up and get idle" ability to save power on a sooner-idle PCIE link after the transmission is done.
Really the PC design is backwards since the GPU is EFFECTIVELY more powerful wrt. any reasonable metric of FLOPS / MIPS / VRAM BW than the PC it is inserted in but it's attached
to the mainboard (and can only communicate IPC or to system RAM) at PCIE x16 bottlenecked speeds well less than what the system RAM / CPU or parallel operating (multiple) GPUs are capable of handling if it were not for the PCIE BW bottleneck. So it is a poorly scaled "primary bus" to have one's most high throughput / performance "peripheral" (ha! more like main processor wrt. FLOPS) located on.

The same Intel Gen 12 introduced DDR5 support (when AMD's Zen3 did not have it). This gave Intel competitive advantage for a period of time, until Zen4 appeared. The point is that DDR5 memory sticks were immediately available together with Gen 12. PCIe 5.0x16 host support is completely out of sync with consumer GPUs.
