I believe Mental Omega 1.0, 2.0, 3.0 and even 3.3 and 3.34 can work on most video cards even dating back to the first GeForce 256 or 2 series era. It has worked for me in my recent rigs (running Win7 and Win10), but when I tried to launch MO (through its exe) on my old Pentium 4 PC, the message reads out that it was unable to detect the video card (but it's already installed!). Well.... I installed the Net Framework 4.0 and even the XNA Framework 4 and DirectX latest update, all on Windows XP Home Edition. I installed this mod with the latest version all inputted into the RA2/YR main directory. However.... both the vanilla RA2 and YR are working without issues. The old video card I am running on my old PC is a GeForce 4 MX 440 AGP 8X.
Am I missing something or was there something incompatible in my old system?
