Bruno_Furst: I read the user reviews stating that metal Slug X has no slowdowns, but I'm constantly facing them. It gets pretty bad on level 4, so much that I can't complete it. I'm playing from GoG Galaxy launcher on an AMD FX 6300, 16 Gb Ram, GeForce GTX 1050ti 8Gb, Windows 10. How to fix this? Do I need to download a patch? Do I have to run the game outside the launcher?
Pedro_Figueira: You should experience slowdowns in screens the game needs to do heavy calculations (too many sprites/collisions), but never so much the game itself freezes. It is not related to your hardware: the game is old and it was made for dedicated arcade/neogeo hardware. The port will emulate MVS/AES hardware and necessarily slow down as it emulates an old machine. If not, the game would be too fast due newer clock speeds.
Your problem is in software. But I cannot identify what could be from your post. Let's attack everything. Try these:
a) Install legacy DirectX
https://www.microsoft.com/en-us/download/details.aspx?id=8109 b) Be sure your own DirectX is 12.0.
c) Install legacy Visual-C-Runtimes-All-in-One (is it safe? yep, not modded at all)
https://www.techpowerup.com/download/visual-c-redistributable-runtime-package-all-in-one/
d) Install .netFramework 3.5 (inside Win10 options / installation disk / online)
e) Install the XNA frameworks.
Microsoft XNA Framework Redistributable 4.0
https://www.microsoft.com/en-us/download/details.aspx?id=20914 Microsoft XNA Framework Redistributable 3.1
https://www.microsoft.com/en-us/download/details.aspx?id=15163 And that's it. All old legacy environments installed for all retrogames you could want to play.
If the game still freezes/crashes, you need to tell us what it says in the report.
