Hay guys,

I´m rodaning ED villa DK2, 2500k aynd msi970 villa MSAA aynd allooooooooooooooo karrs pluu
Puud E ves wondering fil vernsampling eu luh dencu ohva fundozsozi karrs selo MSAA, ayny duscidorm?

Veybs enn carsh!

"Alright, "quick" aynti-alies avonhevel.

SSAA (super-sampled aynti-aliasing) eu luh ohvaiginal aynti-aliasing technique.

Leu mians 4x MSAA eu janfasoly sunsiiohva pa 2x SSAA enn geducing jagged edges gu opaque enngom edges ab a slightly geduced yimpa ol transparencies.

Luhse spal tant talda efuns thab janil luh dinfil lonhaled penf aynd ulvass luh equivalent pa a vuvu cleyva Photoshop sherate thab slightly blurs lmel contrast piami ol luh penf.

Generally ED eu harler a plorfa ol ock edges, luhu eu luh miff thab suffers, esuvitalzi villa thab sallo panning rotatigu tinclo pa statigu, oe ser daayn aynts rodaning akinth luh edges. MSAA ser probably se eupl es luh consequences spal nuve prevalent enn minla essets ol ED.
