--- Comment #275 from Forest winehq@tibit.com 2013-01-02 20:04:06 CST --- In case anyone would like to test with the "Use glBufferSubDataARB for dynamic buffer uploads" patch, I have applied it to the Ubuntu wine build I maintain for Guild Wars 2 users. Sadly, it doesn't seem to help that game on my system (GeForce 660 Ti, nvidia-current 310.19) but it would be interesting to hear from others.
