Releases · sultim-t/xash-rt

Install

1. Buy and install Half-Life (1998) on Steam

   • A clean installation without any mods is preferable
   • It doesn’t work with Half-Life: Source

2. Open its folder

   • In Steam library: right click on Half Life → Manage → Browse local Files

3. Unzip hl1-rt-combined.zip into the folder

   • If you have a previous version of the mod, delete existing rt and rt_bin folders
   • Replace if prompted: so original configs will not interfere with HL1 RT

4. Run rt_bin/xash3d.exe from its folder

   • Press X to switch renderers on the fly
   • To use DLSS, additional steps are required (see below)

Optional DLSS

1. Download RayTracedGL1-Bundle-DLSS.zip
   • Replace the original rt_bin/RayTracedGL1.dll with a new one bin/RayTracedGL1.dll from RayTracedGL1-Bundle-DLSS.zip
2. And download nvngx_dlss.dll
   • Place it into the rt_bin folder, ensure that it’s called nvngx_dlss.dll

If you have an issue, please, try find it in Issues or Discussions, as it might be already solved

Mods

Mods that use special logic (i.e. with custom .dll-s) must be recompiled to 64-bit.
Mods that just replace models or add maps should work, but the lighting might be overly dark and unplayable.
Custom maps must be manually tweaked.
