Can more cores cause lower input lag? And more cpu questions.

[Worstylolzs]

Hello i got question after the long time, again for you.
1) You write yo got 2ccx cpu 3950x/5950x I want to ask you, have you ever try set core affiny for windows and other programs for one ccx and the game on other ccx? If not can you try it plz? If can help have more stable game.
I found video for that, but he doesn't have 2 ccx so he just give windows and programs to two core and other use for games and fix priorities https://www.youtube.com/watch?v=p9xu8u_0Xpk

I've done this and it does help yes -- however some anticheat software protection (EAC) starts to prevent this from being applied/changed.
Unless there are launchers where we can set the rules to the parent process (launcher) and it'll pass it on to the child process. (game client)

I've used various methods and programs to try to achieve this, but none (unless setting Explorer to use on ccd only, which is not ideal.) seem to work.

Last time i don't bought any cpu i was waiting for new generation. Now i will have money and can buy, but again same bad question like before. 7900 or 7700 ? I know i dont want x version because there is so much cpu power on non x and i know don't need 3D because i play games what dont utilize that cache so much and cpu still got so much power. (Maybe later). So my first question will help my to decide. My favorite is 7900 because have another Pros like if i will try streaming or video editing and in future maybe can use for work (im Automation tester with java, but future maybe will be java developer)

I think (personally) for the vast majority of users 8 cores right now with the 7800x(and 3D) will be absolutely splendid for most of those tasks and won't suffer from the issues coming with multi-ccd CPUs.
Streaming can be done on the GPU and video editing scales tiny bits with more cores and threads but DaVinci Resolve for instance can also use the GPU for encoding/rendering the video. and/or development. So these CPUs will suit all your tasks greatly!

I am personally gonna get the 5800X3D as I do play games for the most part and my workload doesn't seem to require that many cores/threads (except virtual machines, but I will likely re-use my 3950x for a separate server-box/machine)

Thanks for answer.

I play apex legends and wow. In this games you can set your affinity to parent procces, so there will be not problem have two ccd cpu if i understand right. Im very curious about two ccds cpu, but i understand more ccd=more problems. In past i said apex is cpu bound game and its not true. It's use maily one or two core, so more cores than 6 or 8 will not pay any advantage there. In the end i can do the same thing like guy on video what i was send. Alocate some different cores to game and to other programs and windows, i can do on 8 core cpu too. I think the game can be more cleaner if cpu what game use will be really alocated only for game and dont do another tasks.

Correct.

Again though like I said, for multiplayer games and some anticheats blocking affinity changes (EAC) it might get difficult(er).

After some time i buy Processlasso payed version and try set on one core on my i7-6700k cpu system and other processes and to next 3 cores set steam and other game launchers. This was amazing! my apex legends feels so much good! From this moment i decide to buy 2 CCD procesor because want set one CCD to games and other to next programs! IDK why windows dont do that on their scheduler automatically. But my try show you dont need two CCD for this settings of core, but i just want it! Thanks all for this thread and helps!

Awesome, glad you're having such an excellent experience.

Just today I was always wondering why apex feels weird, my fps would stay high, my 1% and 0.1% still was good with both CCD's on my 5900x, but there was still this jittery look, as if I was playing with a lower refresh rate, but I wasn't. This morning I decided to try with 1 CCD disabled, and the jittery look is completely gone, before this I tried with only SMT disabled but it was still there (seemed a little better) but this has completely removed that horrible look, it had been bugging me for like a year now. I never really noticed it in any other game then apex.

Anyone mind giving me a quick explanation of what CCD is? I see it used here but not sure what acronym stands for.

Apex gives me issues as well, have been trying to solve for a long time. I have a 10900k and 3090 running at 1440p, I run high FPS but it still feels choppy compared to other games, especially overwatch. Performance is good and I have tried very hard to reduce input latency and improve performance with tweaks.

I use process lasso to set affinity of all programs from 0-3(first four cores) then games from 4-9. I have the virtual cores disabled(I think it's called hyperthreading?). There are a few windows functions which I don't adjust as they give permission errors. I also run all games on high CPU priority. This seems to reduce stutters and improve performance in many games, but has not helped much at all for apex. I see now that others say to simply set the parent launchers(steam, battle.net, etc) affinity/priority and that the games will inherit them. Is this better or equal to my setup? I noticed for some games, lowering the priority for the anti-cheat reduces stutters(without hurting the anti-cheat, of course), so that part I will keep.

Does my hardware/system have multiple CCDs? How would I reduce it down to 1, as in the quote, to test if that improves performance?

I have limited knowledge so please be specific, especially considering how much misinformation is out there, likely some of my knowledge is incorrect or built on incorrect information.

For apex legends check this thread viewtopic.php?f=10&t=10315&p=89858#p89858 i send here video for guy, what wierd frame issues in Apex with reg edit of fullscreen optimization or try DX12 mode.
