If you have an Intel graphic card and you have tried these solutions:
*Running game in Windows 95 compatibility mode.
*Updating your baldur.ini file to show OpenGL 1
*Disabled desktop composition
*Updated to the latest drivers, either through Intel or forcing them through on you system for updating to occur.
And you are still frustrated by choppy video, laggy walk speeds when near water and troublesome spell lag...
Then this is the final cure. I say final as it is quite radical. It works for me on my Intel Core Duo processor with Intel GMA 4500MHD graphics chipset... and it works as this cure bypasses the sorry excuse of a driver for the Intel 4 chipset family.
First read all the instructions and check you are ok with what is asked. I managed to make a mess of it a couple of times, my computer is fine, but I cannot take responsibility if something goes wrong on your computer.
That said and you’re happy... Here we go
You are going to be using Ubuntu, through wubi. A linux package, which can be installed alongside windows. It can run Baldur's Gate Enhanced Edition fine on your computer simply because it uses its own set of drivers meaning the Intel ones are now redundant!
Step 1. Defrag your computer. Use windows own disk defragmenter (I like to use Wise Disk Cleaner)
Step 2. Reboot for the hell of it... You may have updates to install, something in the memory whatever a reboot never hurts.
Step 3. Download Wubi 12.10 from Ubuntu at http://www.ubuntu.com/download/desktop/windows-installer
SAVE IT, DO NOT RUN THE PROGRAM YET ! ! !
Step 4. Ensure 32 bit architecture is installed. For reasons unfathomable to me at present, Wine, an app needed to run on Ubuntu to make BG:EE work will not run with 64 bit architecture installed. You don't even need to know what the OS architecture means or even count to the dizzy heights of 32 and 64 (I don't) as we are going to create a shortcut.
Right click on the downloaded wubi.exe, go to create shortcut. A shortcut will appear. Right click the shortcut and go to target. Simply edit this by placing --32 at the end of the target address. As you can see on my picture it shows C:\Users\Andrew\Downloads\wubi.exe --32
Step 5. Double left click the SHORTCUT to run the Wubi.exe. You will get some options, I would leave as is, although you may consider lowering the amount of your C: drive partitioned to Ubuntu. As a person with a 500GB drive 18GB is not a problem, however you can lower it to 5GB. You will also need to type in a memorable password.
Step 6. Let Wubi do its magic. Warning do not interrupt the magic as it can hurt your computer, in the same way that disrupting a Windows 8 from 7 install will hurt your computer. Please be careful. It took 20 minutes on my machine. It will then ask if you would like to reboot. Say yes. On reboot you will get a simple option screen for you to choose to load Ubuntu or Windows. Choose Ubuntu.
Step 7. You have just installed Ubuntu. Welcome to the world of Linux minus crappy Intel drivers! Whoo! Look top right and click the empty wifi signal / cable connection and connect to the internet using your key code as normal.
Step 8. You will now see a list of icons on the left of the screen. Click the shopping bag to load up the Ubuntu software central. Please feel free to browse at your leisure, but we want to get BG:EE working so click onto the search bar and type WINE.
Step 9. Your search results should appear. Click the top of the list WINE META INSTALL option. Allow it to install. This took an episode of Coronation Street minus adverts to install (25 minutes to the rest of the world). You may also see an icon bottom left with a number next to it... These are updates to the Ubuntu apps already installed. Go ahead and update... Again, as your first run it may take some time.
Step 10. Nearly there... Loading BG:EE. Click on the folder icon near the top left of the screen. You will see the Home folder. At the top is a bar with the word Home with a small < icon next to it. Click the < to go up one to see another screen of folders. Click again on the disc drive icon that appeared where the < icon was... (I will get pictures as soon as I can figure out how to print screen on Ubuntu) Now search the folders until you find the one labelled Host. Click on the Host folder. You have now found all of the windows programmes on your windows C:\ drive! These will all be read only... But that’s all we need. Find your Baldur's Gate Enhanced Edition folder, click. The BGEE installer exe will not run in Ubuntu, ignore it. Every time you run it in windows it will update it as normal, you can then check if they have fixed the Intel issue every now and again before returning to Ubuntu to play. Now open up the Data folder, click. Now open the folder 00766.
Step 11. So close... Now right click the Baldur.exe. On the option choose to load with the Wine up loader option. Easy to spot. It has a wine glass next to it.
Step 12. Weep tears of joy as BG:EE runs flawlessly on your computer, whilst wife asks in a concerned voice about who has died (I did... but then I tried about 14 different versions of the above steps...)
Other things to consider.
You can uninstall Ubuntu really quickly by going to Windows control panel and uninstalling Ubuntu like any other regular programme. Done!
Ubuntu and Wine are both free to use. Donations, although I have no affiliation with the brain boxes behind them, would, I believe, be appreciated.
Let me know of your success stories...
