Pangaea666: Do you have some screenshots or something of the errors? Not paid much attention to the blue circle to be honest, as it's generally bat-shit crazy (and if you move to it, it funnily tends to move somewhere else :D), but I've definitely not seen the only-food icons in city screens.
adamhm: Thanks for posting about this; it looks like I missed some libraries as installing d3dx9_31 and d3dx9_32 fixes it. I'm not sure how I managed to miss those as I did test with the full set of d3dx9_## libraries while trying to solve the other issues, but oh well... it's fixed now at least :)
The grey circle in the tutorial persists, but that's not really a problem as it's very obvious what you're supposed to do at that point (setting UseGLSL=disabled fixes it but causes other problems with the main game so it's not worth doing).
I've attached a screenshot showing both issues anyway.
Pangaea666: Don't think I've played with CSMT (but I don't see that in the options?), and I prefer to play it in fullscreen mode. Works much better with edge-of-screen scrolling, and I "disappear" into the game world more effectively. Heh. Maybe not a good thing. I can play a single game for 50-100 hours.
adamhm: You need a recent version of Wine. For regular versions of Wine you need to set the CSMT registry entry (
https://wiki.winehq.org/Useful_Registry_Keys ) but these don't yet include the full CSMT patchset. In Wine Staging you simply open winecfg and check the box under the "Staging" tab to enable it. Wine Staging with CSMT enabled should offer much better performance.
I'm running the game fullscreen at 1920x1200, performance seems fine (can get a little stuttery in places but nothing really bad so far at least).
Thanks for the update, and I'm glad you got it working :) Very strange bugs in the screenshot you posted. I've not seen that before, but then I have probably never played 'normal' Civ4 either, where the tutorial is. I actually don't have the GOG version, but a store-bought one ages ago, which works well since they removed the CD-check with a patch (maybe the last one, but not 100% sure on that).
I've played thousands of hours in the game, on Linux (no kdding either!), and haven' had any real issues. As mentioned the game can get sluggish in the later eras, especially on big maps (large or huge), but that's not a Linux issue. It's like that for everybody, even on modern computers.
I love the game, though, and recommend everybody with interest in that kind of games to invest in it. IMO, it's the best in the series. Deeper and more complex than the later games. And actually offers pretty darn tough opposition on the toughest difficulty setting (Deity).
Looking back at the screenshots I posted almost hurts, because the superior move would have been to settle on the marble for a 3-hammer city tile (it even retains fresh-water bonus). But oh well, I'm not playing the game right now. Need a break after wearing myself out :D
