Please describe your issue in as much detail as possible:

While forcing cs2 to run on Vulkan renderer (-vulkan launch parameter) it consumes 100% of GPU being on lowest graphics settings.

Steps for reproducing this issue:

1. Set "-vulkan" launch parameter
2. Run CS2 on lowest graphics settings
3. Check GPU usage using Windows 11's task manager

I forgot to mention I use fps_max 0 but it gives me the same fps rate as d3d11 renderer which consumes nearly 80% of GPU at the same settings.

I have the same issue. In addition to this, I have very bad stutters and 1% lows. Initially I thought it was vulkan compiling shaders for an effect on demand but this doesn't seem to be the case even after playing for 2 hours. There should be an option to compile all shaders before hand (I tried doing through the steam ui > download cache) however there seems to be no improvement.

That being said, It could also be that I have no clue about vulkan so I apologize for the same.

I have a weak system, and while I observe the same behaviour, Vulkan actually performs better. DX11 gives me 70 FPS, 80% usage at mid in the new Inferno, Vulkan gives me 110 with 100% usage (under the same conditions, lowest settings 1080p with bots). There's no difference in CPU usage (75-85%). This applies for both the limited test build and the now released public build. Obviously this system is not ideal for the game, but I guess in some cases the elevated usage helps?

Can reproduce on linux, the performance of the vulkan renderer is terrible, to the point that dxvk would probably outperform it by at least 40%. It barely uses my GPU. Valve if you are reading this please integrate dxvk-native into the game and use that as the default, not only does the vulkan renderer have numerous microstutters and graphical glitches, it runs really poorly in comparison to d3d11.

I've noticed that while using vulkan on cs2 it is significantly more choppy and causes lots of micro stutters that can be felt by just looking around. It also uses a lot more system power while only doing 20~fps more than with directx. I don't think the api is a worthy replacement for cs2 yet. I think it needs better support from valves end.

The optimization of the maps are poor. Valve changed their approach to optimazion. There are a lot of locations on maps the player does not interract with but they are rendered for nothing. As I remember previous Source was VERY well optimized now it seems they hired noobish devs. Please hire previous developers.
