[TUNING]: PC Performance not as expected or over estimated - What to do for more performance?

[VitaminZeth]

Every time I play a game in VR, the performance isn't as expected. It's either lagging a bit where I almost get motion sick, or It feels unplayable. The typical check of drivers, bios and windows updates are done routinely, but the MB is an update behind (was a bit lazy). I'm wondering if my expectations shouldn't be as high? Or if there is some fine tuning I should do? The main goal was to hopefully experience 144hz Boneworks and Blade and Sourcery.

Notes: 

- Even with 100% Res and 90Hz, the Valve Index still struggles.

- Coming from a HTC Vive, I still did struggle with performance with the same PC

- Most of the games are running really low settings at 90Hz or 144hz

- I made sure that the misc tasks were done: eg. Temp Folder cleared, Recycling Bin cleared, Boot drive not left with 20GB, Windows Power Profile
- The system has no OC'ing

- SAM is enabled

• Windows 10 Pro 64 bit
• X570 AORUS ELITE (rev. 1.0) (BIOS version F37, Dec 26, 2022)
• Red Devil AMD Radeon™ RX 6950 XT 16GB GDDR6 (Stock Clock)
• 4x16GB G.SKILL Trident Z Neo (For AMD Ryzen) Series 64GB Model F4-3600C16Q-64GTZNC (3600MHz XMP profile 1)
• AIO Cooler (Not sure of the model)
• Samsung SSD 970 EVO Plus 500GB (Boot Drive)
• Games are all installed on either another SSD (x2) or a HDD (1tb)
• Thermaltake Toughpower GF1 1000W Modular Hybrid Power Supply (80+ Gold)

- Bone Works @83fps AVG
- Blade and Sorcery @60fps AVG
- Assetto Corsa (Single Player) @89.98 FPS

That resolution per eye seems awfully high, maybe turn it down and/or enable motion smoothing?

Is your system performing way below benchmarks? I just looked at Boneworks and on a 6900xt it gets above 200fps with 160% steam vr resolution.

 

Seems like something is way off.

Steam VR should be set to auto and then the resolution adjusts on the fly to meet the GPU speed, basically it should simply auto scale to max out the GPU.

Any suggestions on a free benchmark i should use really quickly to see what could be wrong? I wonder if its  thermals, but I really sure as hell hope it isn't. 
And yeah so far.. It just doesn't seem to be performing the way I thought it would be...

unigine superposition for gpu https://benchmark.unigine.com/superposition
 

Cinebench r23 for cpu - https://www.maxon.net/en/downloads/cinebench-r23-downloads

 

3dmark is kinda the gold standard but it is now a paid product (its 5 bucks so it’s not super expensive, but just annoying enough to avoid).

SO I realized I never answered my own question here - It turns out, slap me on the wrist for this rookie mistake, but I used one of those combo cables instead of three separate 8 pins for my GPU. IT was lacking power. How the hell I didn't break something for the last few months is a Really big blessing. After I got it fixed in late May, I was hitting the numbers I would have expected. It was all a "lack of an extra PSU cable" problem. I added the third one and managed to make it work out. 

Thanks again to all those who replied here on this post!
