I did a reinstall of BGT with just the degreenifier as an extra.
My Load times (with the same save files) are down to 33 seconds and my save times to 45 seconds.
I dropped all of my items, wandered through a couple of zones then saved, loaded etc. This made no difference.
I understand that the game will save more data as you progress, I just do not understand this massive jump from a few seconds to minutes. It did not happen as soon as I went to Baldur's Gate City either, just all of a sudden. Yes the city is big but surely my just going into the zones and doing one or two quests should not require more save data than absolutely everything else outside the city gates (barring things I will revisit like Candlekeep but including TotSC).
Is the 90 second+ save game something which always happens in BG1 or is it a Tutu thing. I am not talking about slight increases here, I mean do you get 90 second+ save times with unmodded BG1 Chapter 5. It is not an outdated machine, especially in the context of Baldur's gate.
