Assuming we're talking about the CS:S update:
I honestly can't say I like it at all. I don't care for achievements, end of round MVP and other stats, and I don't really like the new status screen. Overlooking all that superficial mumbo jumbo I'm very unhappy with the engine update. Before the update I had absolutely no problem running the game on full settings on 32 slot servers, now the game constantly stutters even on servers with 12 people/less. My weapon presets all show up dark despite the amount of cash I have on hand, which is confusing as hell when I'm trying to buy my loadout. Since the update my connection on SEVERAL servers has been randomly dropped, and it's not my ISP. There have been numerous occasions when I'll see shots hit but fail to register, and my frame rate has dropped to high 20's - low 30's when I could run at a cool 70 FPS prior. When I enter death cam there is a lot of stuttering with static/dynamic props and when someone has the bomb on their back it looks like it's flipping out and having its own rave/party.
As stated previously: CS:S ran fine before, running everything on high settings. TF2 also functions fine for me on high, so whatever engine changes they did they either didn't do well or the update is just glitchy as hell for me. It's odd because some people said they aren't having the issues that I'm having, while many others claim to have it worse.
The big thing I'm concerned about is just running the game like it used to, I don't care about fancy new stat screens or kill cams, I just want the game to be playable again for me. Until they can work out some of these glitches I'm going to have to take a break, as of current the new update has rendered the game itself nearly unplayable for me...
Like all things software: Issues tend to be resolved over time. I think that they should have kept the beta going for a couple more months, but that's just my opinion and I'm definitely not one of the devs working on this.
I'd complain on the STEAM forums but currently they are overrun with retards "Hurr durr money back" or "dis Iz B3St UpD4T3 EvAR!!!11!1!!ELEVENTY!11!1!!" I'm sure the devs have their hands full currently.
Anyways <3 TD
