"Games" more efficent/stable with 4 out of 6 Cores

[Shixsore2]

Hey Linus-Techtips Forum,

 

 i´ve had this problem for quite a long time.

 

After upgrading to a Gaming-Pc all games would run smooth like butter. My 6700k would hold up 300fps constantly at Csgo and the "way of playing" just felt like a smooth transition from mouse to keyboard inputs. After one to two Years it would start struggling and i wasnt able to figure out why. Holding 300fps in non active areas would become difficult and not to talk about action packed scenes. Everything was non overclocked, had well temps and no abnormalites in stresstests. 

 

Thought to myself, well, got a bad batch and its time was over. Did another full upgrade of ram, ssd (kept one of my old SSD + 1080), cpu and motherboard. 3200mhz 32gb, m.2, 8700k, z370pro, and it just started where i left it. Now, another  2 Years after upgrading and disbelief in Pc-Parts, i figured to try locking 2 out of the 6 cores via startparameter and it ran almost 50% smoother. Still below its actual potential and peak of my 6700k, but it wouldnt struggle as much anymore.

 

I´ve seen Benchmarks from 6+ Core Cpu´s at Csgo with 500+ fps. My piece of * cpu never even came close to this frames. Again, temps are good and no abnormalites in stresstests. 

 

Question is, did i got another bad Batch or something from my old SSD (Windows is on m.2) carried over to the new Build? There is no reason for a game like Csgo run better with less physical cores than available, no?

I don't know about CS:go or high fps gaming in general, but have to wonder if it is a HT thing. HT can increase throughput, at the cost of working a given thread slower. I'd suggest you try leaving 6 cores enabled, but turn off HT. If it scales with thread performance, that may help prevent situations where critical path might get delayed. This assumes the CPU isn't totally limiting.

 

In general, hardware either works or not. Maybe a bad setting can affect things but it is still less likely than "some weird software thing" in Windows, which are extremely difficult to diagnose outside reinstalls which are an obvious pain.

Might be running on HT thread instead of core threads.

 

Did you reinstall or just carry over your windows install? If it is the latter then yeah you kinda screwed yourself over. Always reinstall when moving to a different system avoids A LOT of issues.

This was a issue with csgo but they did some things to make windows allocate actual cores to the game in the past. Unless there is some software bug or weird hardware config.

It´s not HT unfortunately. Allready played around with it as i got my 6700k back then. But what i´ve noticed is, that it is activated by default. It wasnt like this before

Dunno about the reinstall back then but pretty sure i did wipe everyhting and only carried over empty disks.

Maybe >9000 security patches for Intel CPU in the past 2-3 years screws up the performance in CPU sensitive game like CSGO.

Spectre, Meltdown, Zombieload, yada yada..
