Video cards limited to SM 2.0b were already considered "low-end" back in 2008.ĭue to all of this, we are standardizing and forcing DirectX 9 with SM 3.0 in Patch 2.1.2 (also known as "dxlevel 95") for TF2 Classic. To make matters more complex, there are two "shader models" for Source, Shader Model 2.0b and 3.0, and shaders also have to be written according to the shader model the game is using. DirectX 8 shader development is a lot of effort only to supplement a small user base. Shaders have to be written twice, once for DirectX 8, and once for DirectX 9. Unfortunately, this has heavy implications for development. This forcibly disables a number of graphical features, and is popular among configs and users trying to squeeze out extra frames. Ending DirectX 8 Support (Patch 2.1.2)Older Source games usually allow users to set a lower DirectX level using a launch option like -dxlevel. If completely disabled, the game should look the same as it did with HDR disabled. Additionally, this update will add a slider to our video settings that will allow the user to tweak the bloom effect. This should not have a big performance impact. Furthermore, if a mapper accidentally only built HDR data, lighting wouldn't work at all for players using LDR.Īs such, we are forcibly enabling HDR rendering in Patch 2.1.2. This is extremely inefficient, as it makes maps take longer to compile and take up more disk space. However, due to HDR and LDR coexisting, every map has to be built twice. Practically speaking, if you have HDR enabled, that means you're using LDR with bloom and auto-exposure effects. It simulates HDR internally and collapses the image down to LDR. Forcing HDR (Patch 2.1.2)Believe it or not, HDR (High Dynamic Range) rendering in Source is completely different from what would be considered HDR today. Today, we're here to talk about some of these changes. As we aim to improve the TF2 Classic experience for modern PCs, we've planned out some major changes we're hoping to slowly roll out in the near future. Back in 2007, the Wii was still in its prime, the GeForce FX5500 was a good card, and the future of PC gaming was Games for Windows – LIVE.Īfter 16 years, the environment has changed. The year is 2023, and Team Fortress 2 is a very old game.
