I have seen some trains that have 1024x1024 textures and asks you to replace to with 512x512 textures if there is errors. So now I want to ask whether 512x512 or 1024x1024 textures is better. I am running MSTS in 640x480x16 and desktop resoultion is 800x600 in P3 667Mhz(can it handle 1024x1024 with acceptable fps? I get 59fps in the tunnels of baltimore with acela.) My MSTS settings is all default except the object(or was it world) density which is 7. My video card is diamond stealth III 16MB.
