I promised to report back and alas, it didn't work. The games crash with a memory violation using the old OpenGL driver. I also tried installing the Radeon 9700 and 8500 drivers from 2001-2002 for my 9600 Pro by faking the PCI ID, but the drivers fail to load and give lots of resource conflicts.

That's a great idea! I looked into the older drivers and interestingly, their OpenGL driver (ati09xxx.dll) is much smaller than the newer ones (1.0 MB instead of 2.5 MB), so maybe this is the point where they moved to Windows 98 and dropped Windows 95 support. I will try it tomorrow and report back! …

As a huge fan of Windows 95, I have to ask you guys why you didn't give up and just upgrade to Windows 98? It's just nostalgia - Windows 95 was my first OS and I wanted to see how far I could push it, especially with newer 3D games. It's an interesting combo because almost no one running Windows 95 …

I have a Radeon 9600 Pro and at first I couldn't get it to work either with the newer Catalyst drivers. Even though the drivers install without any error message and the card shows up correctly in the device manager, I am still limited to a desktop resolution of 640x480 and Direct3D games don't work …

:/

I found the problem, it's in sdlmain.cpp. When the window loses focus, it calls CPU_Enable_SkipAutoAdjust() and lowers the process priority. When it regains focus, it should call the opposite function CPU_Disable_SkipAutoAdjust() and restore priority, but this does not happen. This was responsible …

Sadly, this hasn't been fixed yet as of Dosbox 0.74-3, running Windows 10. You can try this yourself: Use the default config file, but change this line: priority=higher,normal to: priority=higher,pause Then, start Dosbox and run any game. While playing, press alt+tab to leave Dosbox, then press alt+ …
