Re: After an autosave, the game starts lagging

@zalako Do you actually have 2 separate hard drives, or do you have one which is partitioned into two? Not sure how that would show up on a dxdiag, but given their odd sizes and identical model, I thought it was worth checking. If you have one hard drive partitioned, moving the save folder unfortunately won't rule out an issue with the hard drive.

One drive, partitioned in two.

@zalako Then, as @Fred_vdp said, it's possibly an issue with your hard drive causing the lag, possibly combined with your GPU, which isn't really intended for games like this. Makes it a bit tricky to test, since you don't have another hard drive to try it out with.

Out of curiosity, the version of the game you tried earlier, your friends version on disk, was that on your computer? And did it include the Trespasser DLC? Trespasser does tend to increase the demand on hardware, so computers which could play the base game with no issues can have troubles running it with Trespasser installed (unlike the other DLCs, Trespasser influences the entire game, not just the DLC area). Have you tried lowering your graphics settings, to see if that makes any difference? 

The CD was just the base game, no DLC and I played it about a year ago. I tried installing only the base game without the DLCs, but it made no difference. I lowered the settings to off, low, very low - it didn't help.

What bothers me the most is that the game runs fine and smoothly without lags for about five minutes. And than suddenly after the second/third autosave - lag.

It makes no sense to me. If the GPU were the problem - wouldn't it be the problem since the beginning? And that happens every time I start the game. It doesn't matter how much I progressed or where I am.

@zalako I suggested lowering the settings to see if it helped. If it doesn't, then that likely isn't the problem, especially if it starts happening only after auto saving, which hints more at a hard drive issue. Was worth checking, anyway, since so many issues with this game on PC are caused by the graphics, even if they seem unrelated.

The game has changed since you played it about a year ago. It's likely your computer has, too.

I can't remember, is there an option in the game to disable autosave? It might be a pain, especially if you crash/die in a place where you haven't been able to manually save in a while, but if you can disable it it's worth a try to see if it stops the lag. Not sure it's an option, though.
