Can someone, who has these remakes (from GOG preferably) check whether this same issue (or "feature") exists also in the EE versions? That is, when you are running either game, one of your CPU cores is constantly running at around 100% (or 50%, if you are using HyperThreading)? This seems to be some kind of feature of the old Infinity engine games.

I would have expected that the remakes are designed to handle CPUs differently, but earlier I've seen some EE version players asking about the same. So I am just wondering if the EE versions inherited this "feature" from the original Infinity engine games?

Well, I don't have EE version, but I found this - https://steamcommunity.com/app/228280/discussions/0/864973032860929347/

Oh well, I bought the EE versions, so I guess I will test it myself. Reporting back later...

Yeah I tested it (this time on a HP ProBook 6470b laptop). It seems the enhanced editions, either BG EE or BG2 EE, don't have this same feature, which is good.

The classic versions were constantly using 50% of one core (ie. all the CPU power they can find due to hyper threading I presume; without it the load would have shot up to 100% I guess), while the other core was near 0%.

The enhanced editions utilized both cores, and used much less CPU power (e.g. both cores usually ran at around 5-10%). Hence, the CPU also ran considerably cooler with the enhanced editions than the classic versions, also with less fan noise. Very nice that they fixed this, this alone probably makes the EE versions preferable to me.

It is interesting though that you reported the classic versions using constant 13% of a CPU core. In my case, having tested it on four different PCs, it used either 100% or 50%. The latter apparently is related to hyper threading, in either case the game tries to use all the CPU power it can find.

Can you test it also with Core Temp, if it gives a similar figure (13%)? The utility can be downloaded from the following link, and doesn't need to be installed (it is portable, so just unzip it and run it):

EDIT: Added screenshots of both BG2 classic and EE, with CoreTemp running on the side.

You can see from the screenshots also how BG2 classic uses more power (14.4W) compared to EE (5.0W).

Hi timppu,

Sorry I should have explained better. That 13% figure was how much cpu usage Baldur's Gate 2 classic was using overall of all my available cpu cores. Yeah it was maxing one of my cores, but I have a quad core with hyper threading. So 4 real cores each with hyper threading = 8 logical cores. So 100% cpu usage divide by 8 = 12.5%, which is roughly why I was getting 13% usage overall. But yeah, it was maxing 1 of my cores the entire time. I took some more screenshots while using the program you suggested. The problem with classic maxing 1 core is definetly easier to see here than the screenshots I made before.

I think my attachment names are being truncated so I will list them here.
