Question Huge Fps Drops

[Symb1]

Hey I need an advice how to improve my gaming performance. I was for the longest time playing on 1080p/60hz monitor meaning I capped my fps with vertical
sync (60fps) and I could play smoothly any game on ultra setting 1080p.

However I recently bought 175hz FHD HDR Monitor with Adaptive Sync meaning I no longer need to cap my fps with vertical sync or in game for a lot
smoother gameplay, but now with bigger fps ranges, the difference between Max Fps and 1% Low is just too high for me to ignore. The stuttering/tearing even
with adaptive sync on is really annoying and it results in not so smooth gameplay.

You may be asking why I don't lower in-game settings, but that won't fix the issue.
Let's say on Ultra my 1% is 60FPS and Max is 130FPS, when I lower it to Medium my 1% goes up to 70FPS but my Max is now 145FPS so the gap stays.

My GPU is averaging 95-96% utilization, no idea why it can't go to 100%, v-sync is off and I'm not capping frames anymore.
CPU utilization averages around 50% or so, can spike up to 85% which should still not result in a CPU bottleneck.
CPU Temps are no more than 71°C and Gpu maxes out around 65°C.
CPU + GPU are in default mode ( no overlocking ).
I have SAM enabled.
Power Plan - High Performance ( not sure if it matters, pretty sure games can overwrite it anyway ).
Also I don't have 100% Disk usage so SSD is not causing the issue either.

The oldest part in my PC is CPU that I bought almost 5 years ago, is it worth upgrading or is the issue somewhere else? My goal is to play games on 1080p,
Ultra settings only. Also I don't care about raytracing.

My spec:
CPU: AMD Ryzen 5 5600x
GPU: AMD RX 7600
RAM: 4x8 GB DDR4 - 3200MHZ
STORAGE: NV2 PCIe 4.0 NVMe SSD 1TB

Never look at max FPS. Instead, look at average FPS and 1% low.

Let's say on Ultra my 1% is 60FPS

That is what RX 7600 is capable of on 1080p Ultra.

Whereby average FPS ~81. This gap, between 1% low and average FPS is with ALL GPUs.

My goal is to play games on 1080p,
Ultra settings only.

You can. Either live with fluctuating FPS, since ALL GPUs do that, OR cap FPS to 60.
Or get a FAR better GPU + beefier PSU to go along with it.

175hz FHD HDR Monitor

Only the best GPU out there, RTX 4090, can achieve average FPS past 175 FPS on 1080p Ultra.

RTX 4080 Super also barely makes it. But there always will be fluctuating FPS between average and 1% low.

With RTX 4090/4080 Super, you could cap the FPS to 120 and have constant FPS without fluctuation, but none can do 1% low at 175 FPS on 1080p Ultra. At least, not yet. Maybe RTX 6090 could do it.
