I don't speak English very well too, and I'm sure you can make some effort for it.
And you know, there is something called translators.

By the way, I tried to translate your message. And I want to ask : what settings have you changed, especially?
IMO, you should turn off AA (antialias) on Opties -> Grafisch -> Volledige antialias -> click on geen
Same for Texturrfilter / AF

And for finished, put Gebruiker LOD to the minimum (for me it's 0.40)
Hopefully it can help you
