Step 1. Cap the framerate to your monitor’s refresh rate
This method works for Hitman: Codename 47, Hitman 2: Silent Assassin and Hitman: Contracts.
For Nvidia users, use Nvidia Inspector
How to configurate Nvidia Inspector:
Summary
Start up nvidiaProfileInspector and from the drop down bar next to Profiles: select the game you want to limit the fps
Under Sync and Refresh set the Frame Rate Limiter to the value your monitor refresh rate is. Mine is a 60Hz monitor so I set it to 60.7fps.
Step 2. Force Antialiasing and Anisotropic filtering. Force both Antialiasing AND Anisotropic
only for Codename 47, for Silent Assassin and Contracts force ONLY Antialiasing!
Summary
Similarly with capping the fps, use Nvidia Inspector.
Note: Seams will be visible on 47’s model and text might be difficult to read with this enabled.
For Antialiasing to be forced in Hitman: Contracts, follow the previous guide and under Compatibility: set Antialiasing Fix to On and in the Antialiasing compatibility drop-down menu paste 0x000020C0
Step 3. Configurations for each game separately
Hitman: Codename 47
Summary
- Widescreen and draw distance patch. Password: h47
Simply extract the files into your game directory, open h47.ini and set the desired resolution
[MAIN]
Width = 1920
Height = 1080
For the draw distance, you can keep the default value of 8.0 but for the Colombia and Rotterdam missions I recommend lowering it down to 6.5 since the game might start to lag.
