Here is what I did to try making it work
1) I have un-installed readon fury X and use readon 290X graphic card
2) installed the driver Catalyst 15.7beta
3) started DCS 1.5 ,it works very good
4) Exit DCS 1.5
5) change the driver to Catalyst 15.15
6) started DCS 1.5 ,it works very good
8) Exit DCS 1.5
9) un-installed ç and use geforce titan X graphic card
10) installed the nvdia driver 358.50
11) started DCS 1.5 ,it works very good
12) Exit DCS 1.5
13) un-installed geforce titan X and use readon fury X graphic card
14) installed the driver Catalyst 15.7beta
15) started DCS 1.5 ,oh yes it does‘t work
16) change the driver to Catalyst 15.15
17) started DCS 1.5 ,still have problem
After this, I think may be fury X have HBM memory,readon 290X and titan still use GDDR5 memory so didn't have this problem?
