Massive performance drop in various games (Shadow of the Colossus, Call of Duty 3) after PR #8175

Win 10 1909
i3 6100 @ 4,5 Ghz
16 Gb RAM
GTX 1063
Also the sound became from being perfect to a stuttery mess. But it's because the performance drop.
10358 (before):

10361 (after):

Even more severe case:
10358 (before):

Performance were fine, although with graphical artifacts.
And now after. It's not that it won't go ingame. But with that speed it would take forever:

Did you check with 10377?

[elad335]

Have you tested latest master?

[elad335]

And upload full log.

10377: no changes. Also loading time now is HUGE.

Can someone with more threads test this as well?

I'll check on my 1700 in a bit

Before optimizations PR:

Current master:

That's the only camera angle that gives me sub-60fps, and it's the same before and after the PR

[elad335]

Unfortunately I suspect this issue will remain open for a while, the mentioned pr makes better use of more threads and potentially worse on less threads.
I don't currently plan to change this.

I've added CoD3.
I actually wanted to make an issue about flickering textures at first. But I couldn't get there :D

Hi, sorry if i'm posting in the wrong place, but i have the same to report as the OP.
Cpu:ryzen 3500x
Gpu: 5500xt

Since #8175 i've a massive drop in performance on motorstorm 2, and my cpu usage changed a lot increasing up to 5 to 15 degres the temperature of the cpu.

I can confirm this issue. Running Street Fighter X Tekken I get constant 60fps in rpcs3 0.0.10-10358. But from build 0.0.10-10361 I get fps fluctuating between 26 to 50 fps.
Before

After

Specs:
CPU: Intel Core i5 8600k @ 4.3Ghz

This is still an issue and it happens on every CPU, including my 9900KS.

[elad335]

try tweaking SPURS max threads.

[Yahfz]

for some reason performance is awful with block size mega, but good with safe + preferred spu threads on 6

[elad335]

Test with #8358 and report your results, remember to report results with the new setting as well.

I added the line 'SPU GETLLAR polling detection: true' in the game's custom config and launched the game:

In SotC it seems things get back the way they were before.
COD 3 is also improved a lot. Now I'm getting the former performance with SPURS unlimited.

[elad335]

Thanks for testing, but please report in the pull request next time until it is merged.

Using "SPU GETLLAR polling detection: true" worked for me.
