New 1600$ PC build and I cannot figure out why old PC outperforms it gameplay wise?!?!

so core 0 apparently has the highest dpc count is it normal for a single core to have that much relatively? or is this a driver issue where it is timing out and creating a lot of interrupts?
That is high dpc latency even for amd. On my amd system i was able to bring it down to 0.5 avg.
Use interrupt affinity to assign your workloads to different cores. Assigning GPU to the fastest core is one of the things i noticed that brings down dpc latency by a huge margin. Enable turbo boost ( again, a huge step in lowering down dpc )
sorry im a total noob how would i go about using interrupt affinity is that a third party program? and how would i assign gpu to my fastest core? and i think i do have turboboost enabled.

also i reenabled hpet and the dpc didnt really go down it just started showing dxgkrnl.sys as the most referenced driver. Any insight on what that means? i also disabled the d.o.c.p profile and put my memory at stock speeds and at first this seemed to help but after about 5 minutes it returned and its like once its there it just compounds itself idk i think i definitely have something wrong software wise.
Download Interrupt Affinity Tool. Google it. Most likely your GPU will be assigned to Core 0 and we have to sway away that congestion from that core. Assign your GPU and it's PCIE to any other core except Core 0 and you should see a significant reduction in dpc.

Enabling/Disabling hpet does nothing as per me. Makes zero difference.

Tomorrow I'm gonna try swapping out ram and seeing if it does better. I just had hoped maybe it was some driver issue.

Keep replacing all the part until you find out the part that’s causing the lag then you would know where to focus on and what to do with that part.

my gpu brings up an error with the affinity tool "unidentified affinity mask"

as an update i tried disabling above 4g decoding and resize bar and i still get high dpc latency from
Highest reported DPC routine execution time (µs): 123.040 (dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation)

if anyone can point me to how to clear up these driver call hangs itd be much appreciated.
i will try to ddu my graphics drivers but i have tried two different driver versions so far and im getting the same issues with the same dxgkrnl.sys.

i tried updating many other drivers by going direct to manufacturers website like realtek but same issue persists.

{update}

i recently reseated 6700xt to make sure, and also removed one of the two kits of 2x8gb ram..... the ram wasnt an issue and my dpc is actually higher now referencing the same process. are the numbers just normal????? it seems high i really dont want to put the 1070ti back in my system and redo all drivers again but i guess im going to have to to know for sure.

i really dont wont to throw parts at it but with 2 memory sticks out of the system i dont have a stable docp profile. it would not boot at 3200 today so i guess i will buy some cheap ram. do yall know any drivers i might be missing?

Show the RAM specs in HWINFO please, we can probably tune it so it works better.

i figured out its not a memory issue i swapped graphics cards and nvidia seems to have the same issue and its also widespread on the internet with new drivers. im rolling back to the same drivers i had a good experience with before and if the same issue arises i know that this is 100% coming from the windows update to 19045 build that is effecting windows 10 and 11 users. its just so weird that it seems to only be certain people effected.

heres to hoping a windows update gets forced out or a new driver release. im going to do some more testing on the 1070ti to see if the input lag is any more bearable it just sucks to sink so much money into a system that doesnt perform in the way i had hoped especially after 4 years of gaming on a cobbled together system. at this point and two weeks of sinking my freetime into optimizing this hoping for performance im honestly just burnt out on esports pc gaming all together.

If you still have your old PC, put that 5800X3D in it.
VG258QM 280Hz TN (main)| XG2431 240Hz IPS | XL2540K 240Hz TN | XV252Q 1080p 280Hz IPS | XL2546K 1080p 240hz TN | AW2518HF 1080p 240Hz TN | XV240YP 1080p 165Hz IPS | XG2402 1080p 144hz TN | 27GL83A 1440p 144Hz IPS | XL2411P 144Hz TN | XF240H 144Hz TN

Set your mouse to 1000 Hz and do a quick test.
I got 5800x3d and 3080ti and razer viper v2 @2000hz polling. No lag nor stutter fps capped at 370.
