--- Comment #13 from Rudolf Mayerhofer rm@eightyfive.net 2010-11-06 11:33:42 CDT --- Just compiled the latest git version of wine and this allows me to enable sunshafts in d3d9 mode. This also changes the error on liquid detail tooltips to "Update your graphics drivers" for levels above "Fair".
Simply bumping the nvidia driver versions in wined3d's directx.c to the latest windows versions allows me to select everything up to ultra settings in d3d9 mode on wine. Only problem here is liquid detail above "Fair" produces no water effects at all. Seems like something is missing somewhere to support this.
