I wonder if anyone can recommend other alternatives, though I did see someone say that the Linux drivers run OpenGL really well, and wondered if there's ever been a port of those back into Windows (if so, I haven't found it). I have tried it with the Amernime custom drivers, but didn't see an improvement. Given that objective, are there any alternative drivers or tweaks for GCN video cards that would improve OpenGL performance? On the newer cards it's been patched, but the old ones with the legacy drivers are dreadfully slow. So, the question: could she expect better OpenGL performance by forcing the computer to use the integrated graphics instead of the GPU? I'd prefer having the GPU doing the work, ideally, but if it's just not fast enough then it's a hindrance, not a benefit. Her computer has an old-but-capable Intel i7 4790 processor, with HD4600 graphics.

but she still floats around 20-40 FPS without any real consistency. I've tried to help her tweak graphics settings, installed Sodium (an alternative, faster renderer for Minecraft), reduced RAM utilization, etc. She has my old Radeon R9 290 video card, which is a fairly competent GPU for DirectX games that she plays, but it's very slow with OpenGL. I run a Minecraft server for my family with some mods on it, but my daughter's PC is at her mom's house, and she often complains about the game being slow and laggy, and I've for sure ruled this out server-side.

AMD's older drivers for the Graphics Core Next architecture severely underperform on OpenGL apps, such that games like Minecraft are lucky if they can surpass 40-50 FPS, let alone staying stable around 60. I know the title might sound absurd, but hear me out.
