A Valve Linux Developer Managed Another Small Performance Optimization For RADV

Mesa is for 3D acceleration. ddx is for 2D acceleration, drm drivers are hardware support. Are we done with making apple with orange comparisons?

Strictly speaking Mesa is for OpenGL acceleration and can optionally be used for other things (we put our video encode/decode drivers there for example), primarily when those "other things" share lower level driver bits.

You forgot horrible keyboards. Lenovo managed to make bad keyboards as of late (layout, F-keys being multimedia keys, tiny cursor keys, no print screen (SysRq) and so on). Or just bad haptic feeling, though I guess Lenovo is still better at that than most others.

On my lenovo 310 (amd APU) you can swap the F-keys and multimedia keys in the UEFI settings, so that by default when you press F1 it does F1 and not "sleep" or whatever is its secondary function.

Can confirm the haptic feeling isn't great on the 310, but then again it's fine for a 500-ish laptop anyway.

Matter of taste I presume. I really like Lenovos keyboards, and as a developer can't live without PgU/D next to the arrow keys. Great for reading. There is print screen, between right Alt and Ctrl. Fkeys is a minor inconvenience, I agree. Ditching hardware speaker mute, volume +/-, and microphone mute is a wrong move to me.

I've got a t440p on my desk at work (haswell quad-core, 16GB ram, 14" 1080p, 480-500GB SSD), and an AMD-based equivalent at home would be just splendid, especially if they can share docking stations, chargers, etc.

A485 should have all of these. Using T430s currently, couldn't be more happy. Intel an a little bit old, but still rocks.

... Ryzen APU notebooks ...

Just don't gimp it with single-channel memory, spinning drive, crappy screen, or small battery. The 13" Ideapad 720s looked almost good enough to buy until I got to the single-channel memory part of its specs.

I am personally waiting for Ryzen Thinkpad A485 coming in next couple of months.

Yes, please. I need a new laptop, and a 14" Ryzen APU thinkpad would be perfect.

Edit: A little research shows me that the A485 should arrive in Q3. I can probably stretch my (dual-booted) 2009 13" Macbook just a little longer, as long as an end-goal is in sight.

I wonder ... wouldn't it make more sense to improve AMDVLK instead of porting the goodies of AMDVLK to RADV and essentially create two equal-good vulkan implementations for AMD GPUs?

amdvlk runs the big games (and even has "profiles" for games), but otherwise it does not work well. As mentioned, it fails with dxvk. Now SteamVR's vrcompositor itself runs on it, but if you start any steamvr client application, it fails.

Why does it matter that it's not part of Mesa?
The various ddx are not part of Mesa, nor are the drm drivers, or libdrm, and yet you use all of them without any issue.

Mesa is for 3D acceleration. ddx is for 2D acceleration, drm drivers are hardware support. Are we done with making apple with orange comparisons?

Some textures. Made a quick screen-cast. Sorry for the low quality though. Happened to have OBS set to 720p, but the issue is clearly visible. Also, performance is really bad now for some reason. I used to get close to a hundred FPS average, which I still do if I switch to OpenGL, but Vulkan has dropped to about half.

I don't have this with Polaris.

That's how amdvlk looks with Wine+dxvk and the Witcher 3 (but it works OK with radv):
