Here is how i got my old crappy hd4350 (old pci slot) hardware acceleration working, dxva win7/8/10 32bit, not yet tested on 64bit but i think it should work also, my mobo is kinda crap coz its intel d425kt with onboard atom cpu, i was able to get 1080p movies working What i used: Catalyst 10.7 32bit (if u got 64bit system u should get 64bit) Catalyst 13.12 32bit (if u got 64bit system u should get 64bit) Digital Flem Legacy Modder tool Guide and Download (google it) U need to download drivers and tool. 1 Get your gpu working using Catalyst 13.12 (u should have it, must be this driver version) (u may use windows 7 compatibility mode on windows 10 on setup.exe) 2 Extract Catalyst 10.7 using installer(do not install it) 3 Follow instruction guide and mod driver 13.12 using 10.7 4 Use display driver uninstaller in safe mode and remove all amd driver 5 Restart 6 U need to go testmode to use unsigned drivers Command Prompt as admin and: bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS bcdedit.exe -set TESTSIGNING ON 7 If u are in test mode u click device manager graphics update driver select driver u modded 13.12 for me its Radeon Hd4300/4500Series (FLEMMOD) 8 Restart U are done. Warning: Catalyst Control Center may not work. Youtube 1080p videos works under Internet Explorer, dunno why Chrome dont want to Dxva Checker may give u error, but dont worry dxva should works fine Tested on VLC, Media Player Classic Home Cinema using K-Lite_Codec_Pack_1185_Mega Codec u need to enable DXVA Native on codec setup. Kodi works also as other stuff what use DXVA. on Chrome also decoding should be green in Chrome://gpu tab without using #ignore-gpu-blacklist All tested on 1080p videos. Tried to mod few driver versions. this combination of driver versions give no screen tearing while on desktop, and no bsods on windows shutdown/restart. Hope it will help someone.
