I just finished installing Windows 10 on a custom desktop:
Motherboard: AsRock Z170 OC Formula
CPU: I7 6700k
GPU: Titan Z
I get an error when trying to start the game, it says about a security error (8016). I looked up the error type and found it was an issue that Skylake processors aren't compatible with certain games (old ones I guess). However, an update should have fixed that. I updated my motherboard, but to no avail.
Just one other thing, obviously I mentioned that I'm using a Skylake processor (I7 6700k). Would that processor work for mods that expand the AI functionality, like Misery?
I notice that in the fisrt 10 minutes in game I get around 100 FPS. However, the FPS starts to dim down eventually to 30-50. I use MSI Afterburner to monitor GPU and CPU. The GPU isn't the problem, because it's well below temperature limit. It seems the CPU is having trouble, that or a memory leak. I use a liquid cooler for my CPU.
*Update: When monitoring the CPU usage, it appear that only CPU 1 is reaching 100% usage while all of the other processors don't seem to be doing anything.
Yes, I just found out that CoP engine only uses one core. I'ts not a problem when running vanilla game, but when trying Misery the frames begin to deteriorate.
I never had this problem when I used my old processor, a 2008 I7 920 2.66 GHz., and I also ran it with Windows 7. My new processor is obviously better in every way than the old one, so maybe Windows 10 would be the culprit?
I haven't noticed less performance with it on Win 10 compared to 7 or 8.1. As for the processor you have the fastest single core performance available for gaming so I can't see that being the problem, I have the 4790k which is technically 2 generations older, It's got a 4.6 overclock which should make it's single core performance just about match the 6700k at stock speeds and it flies but Stalker mods still struggle due to the game engine not the PC.
The things that Skylake has over older gens are it's memory and it's storage speeds so to get the most out of it I'd get 16 gb's of the fastest ddr4 available and an M.2 ssd like the one in the link. Skylake is capable of getting the speeds on offer unlike older gens such as mine which does have M.2 capabilities but can't get maximum speeds like Skylake which can manage read/write speeds of 2000/1000 mb/s. Thats where you'll really notice a difference compared to your 920.
