So I´ve finally decided to install the classic Hitman games on my “new” (i.e. 3 years old) laptop to replay them again, and so far I haven´t been able to get either one of them running in a satisfactory manner (that is in 1920x1080 widescreen, fluently, in max details, and - if possible - with antialiasing). After 3 or so hours of tinkering with possible fixes and changes, my blood pressure has just about had it, so I´d like to ask you guys for help if you could share your tips/instructions on how to get them running properly (including things like compatibility, fps lock, GPU settings, etc.).
My main issue atm is with Contracts, which is why I´m posting the thread here rather than starting three separate ones, but I have issues with C47 and SA as well. I´ve got Windows 10, an Nvidia GPU, and all three games are the GOG versions (I have the Steam ones as well if that helps anything).
The main issue here is that the game suffers from a sort of microstutter where it “freezes”/lags for about half a second (maybe even less) roughly every 10 seconds (I sometime experience a similar problem with other older games if I have them installed on the HDD, but not when they´re on the SSD - which is the case of the Hitman ones). Also, the framerate seems somewhat low and the game isn´t nearly as fluid as it should be.
The issue only disappears when I switch the game´s rendering from D3D to OpenGL, but then it loses all the visual and weather effects and the cutscenes and loading screens are completely messed up. I´ve tried capping the framerate to 60 and switch compatibility, but to no avail. Also, the issue is there regardless of whether I run the vanilla version or with a widescreen fix, but seems to be worse with the fix.
I have very much the same “freezing” problem with Codename 47. Again, it´s only in D3D and disappears if the game renders in OpenGL, but then I can´t run the game with the widescreen fix (at least not the one by nemesis2000 that I downloaded).
EDIT: When using the widescreen fix in C47, there is also a massive drop in framerate when looking at buildings etc.
EDIT 2: H2SA has the same lag issue. Actually the most severe one (0,5-1s). And again, regularly every 10 seconds or so. Using D3D rendering and no widescreen fix (haven´t tried it yet). Again, it´s not there in OpenGL, but I heard OGL causes graphical glitches in the game, so it doesn´t sound like a long-term solution.
Any suggestions? (@MrOchoa on C47?)
