In resolution 1024x768, I have a problem that is perhaps playable though recognizable. The text creates small lines perforating between words and letters. I've taken a glance through the forums to no avail. Is anyone experiencing or, I hope, experienced and ameliorated the problem?

My specs:

Lenovo y580

Processor i7 2.36 ghz
Graphics: integrated Intel hd 4000 and Nvidia Gtx 660m
Mem: 16 GB
OS: Windows 7

I have the same issue

I've got the same issue.

Pretty sure it has to do with resolution - the text was fine at 640x480.

I've noticed that when first playing. Playing in 640x480 is almost too intolerable though. Rather than blurry resolution that obfuscates objects or texts in textures, the mild distortions in text boxes fair well in comparison. Both cards on my computer present the same issue; it may lie in the resolution alone.

This might not be right, but it seems like the game was built for two resolutions: 640x480 (low-res) and 1280x960 (hi-res). With other resolutions, the UI doesn't scale well or something.

That is exactly right!
It was designed specifically for those two resolutions. The others are available at your own risk. Over the years I have heard of all kinds of weird problems associated with the non-standard resolutions.
