Sis Mirage 3+ isn't supported?

I just installed the latest drivers from www.sis.com now after a reboot screen goes blinking and I cant do anything else. Metro is having trouble with the latest drivers coz desktop mode had no problems(I managed to get to desktop mode after I reinstalled win8 then installed the latest sis drivers after successful install I disabled it from device manager then reboot and enabled the drivers once am in desktop)I noticed the default display drivers got 256mb shared system memory while latest sis drivers got 60mb of memory so maybe metro is above 60mb so it cant display properly. Am I really stuck with this default display drivers? Cant watch movies properly with these default stuff.Do we have some solutions or remedies here? please help
