Minecraft slow in Arch, fine in Ubuntu

And I can't tell why. Open-source driver. lspci -v:

01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series] (prog-if 00 [VGA controller])
    Subsystem: Acer Incorporated [ALI] Device 0124
    Flags: bus master, fast devsel, latency 64, IRQ 18
    Memory at d0000000 (64-bit, prefetchable) [size=256M]
    Memory at f0100000 (64-bit, non-prefetchable) [size=64K]
    I/O ports at 9000 [size=256]
    Memory at f0000000 (32-bit, non-prefetchable) [size=1M]
    Expansion ROM at <unassigned> [disabled]
    Capabilities: [50] Power Management version 2
    Capabilities: [80] MSI: Enable- Count=1/1 Maskable- 64bit+
    Kernel driver in use: radeon
    Kernel modules: radeon

I've tried both Sun and Open-source Java. No difference. Been following the wiki pretty closely. Everything else having to do with graphics and X seems to work fine. Just let me know if more information is needed.

You probably need this: https://wiki.archlinux.org/index.php/ATI_Catalyst.
Ubuntu installs proprietary drivers automatically.

Re: Minecraft slow in Arch, fine in Ubuntu

Ok, I did not know that. I couldn't tell because that command just says "radeon" for the driver in either system. Thank you, I will give it ago.

I suppose I could have have tried that before posting, but I've been at this for a day or two and got a little hairbrained with what I have and haven't tried and remembering everything there is to try.  x_x

Re: Minecraft slow in Arch, fine in Ubuntu

aticonfig says "No supported adapters detected"

what do?

Tried this once already, and a restart led to no working x.

Re: Minecraft slow in Arch, fine in Ubuntu

Actually, the proprietary driver is NOT installed on my Ubuntu, and I'm pretty sure my card is too old to be supported by that driver. I've reinstalled arch, because idk what I was messing up, bouncing between the two drivers. The open source driver is installed now. Problem persists. If I run glxgears, the framerate in Ubuntu is at least double the speed in Arch.

Idk what I'm missing. If I've not posted some information I should have, sorry. If I've not done something obvious, sorry. Just tell me what I need to do.
