Patch 8.10 LoL is being a bit slower - and I'm missing some audio sounds...

I patched the client as normal Everything went as normal as it always does.

Played a few games and have noticed a few things.

1. When I "alt tab" out of full screen - my previous program comes up instantly, BUT when I click back onto the LoL game - It goes black and takes about 5 seconds to load me back in - It isn't game threatening but it has never done this before and has only started since patching 8.10
2. I noticed that when I recall, My audio is normal until I reach the fountain right at the end - I am missing that big sound "boom" when you get back into the fountain. The "whooooom" as you land is missing.

Just a few things - They aren't game crash or game ruined worthy but it's noticable...

Just hoping you guys on the bug team can find out what's up - My PC has not changed at all - literally only happened after this patch so I don't think it's me

Thanks and rek those "yasuo mains" xD
