Got a bit of nostalgia and bought GTA IV during the last Steam sale. I've heard the horror stories but figured I'd give it a go. It does not run well, at all. I have a modest set-up (1650 Super, Ryzen 5 1600AF, 16GB of RAM). Here's what I've tried so far:
A lot of people suggested using DXKV, which did make my frametime graph much smoother, but made stutter much worse any time I moved (I assume it has something to do with how it loads stuff).
I just want to make sure I've exhausted all options. The issue is that the framerate is just all over the place, even with caps. I'll go as high as 100fps in some sections, and drop to 40 for seemingly no reason.
- GTA IV Definitive Edition mod (DX9 and DXKV)
- This use FusionFix
- Applying FusionFix, Ultimate ASI Loader, Col.Accel
- GTA Downgrader to 1.0.8.0 (DX9 and DXVK)
- This uses ZolikaPatch, which is apparently better than FusionFix
- GTA Downgrader to 1.0.7.0 (DX9 and DXVK)
- Same as above, but was apparently supposed to run better in Vulkan (it didn't)
