Seems to be a really good update. I've only done some brief testing but the "full shader comp" took only 18 mins on my system, and load times feel snappier too although I don't have any specific metrics to compare that with.
On the performance though, CPU performance seems to have massively increased. In the opening section of the game, running through the town, it could easily drop into the low 40's for me previous and now it's mostly locked at 60 with the odd dip into the mid-50's on a couple of the set pieces. And that's with every setting at Ultra, I will try tweaking some of the CPU heavy settings to High to see if I can keep a constant 60fps lock. Extremely impressesd.
Darn, I just finished it last night on my 5600x/DDR43600CL18/3080 10gb rig as I was getting tired of waiting for another patch.
To its credit, even with the last patch, it performed great, with every setting maxed out at 1080p on my 60hz plasma. I could only count a handful of times where it dropped below 60fps, the snowy section with the deer being one notable one.
I got excited when I finally fixed my long standing intermittent performance problem, which turned out to be my problem rather than the fault of the game. I have an almost 10-year-old 1TB SSD that I use to store games on, and I got 3/4 of the way through TLOU part 1 while having horrendous freezes - most commonly during cutscenes, but they'd happen during gameplay too.
For multiple
seconds at a time (10-20) either the entire screen would freeze with audio playing in the background, with CPU and GPU load dropping to near zero. It'd happen every 30-45 minutes, and when it happened in cutscenes, the cutscene would continue to play audio, except nothing would animate. The characters would be frozen in whatever pose they were in, and new content wouldn't load in if there was a cut/transition between areas in the cutscene. Some pretty intense internet searches turned up precisely zero people experiencing the same thing.
After much swearing, turns out that my ancient SSD had some spots where a single 4k read would take upwards of 1500ms (yes, 1.5 seconds!) to complete. I'm actually incredibly impressed that even with a nearly dead disk essentially stopping background asset streaming cold that the game didn't crash once, and these 10+ second freezes happened dozens of times. Good on ya, Naughty Dog / Iron Galaxy!
I might migrate the game back to the SSD just to see if I can try to capture some videos of the madness, it was pretty hilarious watching a cutscene with frozen animations.
A custom SSD with a controller that exposed programmable caps on performance (both in sequential/random reads and in access time) would be a fun tool to have in any QA department's arsenal.
