Final Fantasy Tactics: The War of the Lions

[Accel]

Hello, i have some problem with this game, can anyone please help me find solution?

I played with settings a bit and managed make game look preety and run on ok speed, but there is an annoying problem. Textures seems to "load-up" every time action happens, text-box appears. They looks pixelated and next moment, 1-2 seconds later - smooth. I attached some screenshots to illustrate it. How can i make them smooth all the time and not pixelated at the start? Thanks in advance, any suggestions are much appreciated!

Tick "Lazy Texture Cache" or something close
Im too lazy to check the setting's name if Im right or not
