I finally reinstalled GW2 since I recently had to reinstall my OS as well. I got to "test" my newly-purchased GTX 670. Well to my surprise I barely have any performance improvements. Specifically in GW2 that is, in other games it's literally double or even triple the performance I used to get with my previous GTX 285. I looked at the GW2 forums and it's supposedly a common issue, and the devs seem to point at out the game is heavily CPU-bound. I read most of their tech support-related facts (Q&A section) and ultimately it looks like whatever the system you happen to have GW2 just doesn't run "that smoothly". Is that the case for everyone? I mean I DO see some performance improvements here and there but not that much. The one example I can give is in Queensdale by the bridge near the auction house merchant, if from the merchant's position I look towards the bridge I get no more than around 45FPS, and if from that same position I rotate the camera to a 360º rotation the frames suddenly crash down to the low 10's, but within that same rotation if I stop at any angle the frames will pop back up to around 45 or so, or at most within the 50 FPS range. In Lion's Arch just as I spawn in the map after fast traveling to it at the main gates waypoint and just open the menu to look at the FPS from there then I get around 40FPS, and as I move around the map it goes up to no more than 50FPS or so.
I do remember well enough that under the same in-game settings (maxed) and screen resolution (1680x1050) I used to get no more than 25FPS or so with my GTX 285 in the worst case scenarios, and usually maintained a 35FPS average everywhere else. So with my 285 of course I had to reduce in-game settings but I did get 60 to 70FPS if I reduced the resolution, shadow and reflection settings (however I did still just test the maxed-out settings with the 285 out of curiosity for later comparisons for when I would get to test my 670). In one of the low FPS issues-related threads I read at the official GW2 forums one guy replied to the original post with "welcome to the club!". I wonder is that really common? I wouldn't be aware since basically I'm really out of the loop, information-wise and common/known issues-wise with pretty much any games out there recent enough and in relation to recent GPU architectures and generations. Remember I skipped all generations since my 285 until just barely two days ago when I finally received my 670, so I did miss a lot in between and got stock playing older games most of the time (well I did play recently-released games too, I'm just exaggerating a bit, although for most recent games I had to reduce a good bunch of settings to get smooth game-play, and not just the resolution, but shadows and distance LOD settings and so on)...
So basically, I guess that I'm asking here, to anyone running the game on a similar system (compared to mine in my sig), do any of you guys also experience what you'd call "abnormally low" FPS issues in the game when in fact your system does perform as intended for everything else, including other games too?
As a side note I just ran a default settings 3DMark 11 test and I scored 8207, which for all I know so far seems to be within the "expected scores" for similar systems (is it? I'm not even sure). Note, however, that nothing in my system (literally, nothing) is over-clocked (even the CPU/Motherboard frequency boost features are turned off and the CPU always stays at 3.4Ghz no matter what). But I,d guess that even a stock i7 2600K wouldn't exactly be a problem. As a final note, just to mention, I increased the resolution to 1920x1080 out of curiosity (which my current monitor does not officially support, so I am not using that resolution to avoid potential damage to the monitor, especially in relation to refresh rates and "out of frequency" issues when I use that resolution) and the frames at the same locations and in-game settings remained about the same, sliding down to the 10's when rotating the camera, going up again within the 45 to 55 range when standing still.
Anyway... maybe it's also related to the drivers though? I'm using the latest (and remember, my OS is freshly reinstalled, all latest official Microsoft updates are in, including the service pack of course), latest chipset and sound drivers, etc (all the basic "optimizations and configurations" have been completed prior to installing the game itself). And, I guess I should mention that the NVIDIA Control Panel's options (3D options, PhysX) are all set at default, except for the GPU's performance which is set to "Prefer maximum performance" instead of "Adaptive", but that's it, no other options are forced to override anything in other applications.
So... I guess I should just ask for a drink now that I'm at the bar with everyone else on this matter?
EDIT & UPDATE: Well it looks like leaving the "Reflections" (in-game graphics settings) to either simply "None" or "Terrain & Sky" as well as leaving the "Shadows" setting to anything but "Ultra" (I left mine to "High") greatly helped my case. Doing just that (and absolutely nothing else, leaving all other settings maxed-out) completely removed the sudden FPS drops-to-a-slide-show effect I was getting when rotating the camera fast enough. Now, when moving around and turning the camera everything remains smooth enough. Additionally, doing that increased my overall FPS performance by approximately 10+ FPS depending on my location (and the number of players on-screen, of course).
I think that ultimately, however, overall performance in Guild Wars 2 is (to my personal surprise) not quite good almost regardless of your system. And I do believe that specifically the Reflection's "All" setting, as well as the "Ultra" Shadows setting both need to be tested further by the developers, since I think that those two settings alone will cause most of the performance-related issues that a lot of people seem to be describing on the official forums. I'm still happy nonetheless that I've finally been able to remove that annoying sudden FPS drop issue I had and overall got my extra performance compared to how the game was running previously on my GTX 285 (now I can truly say that it's just overall faster, albeit I did expect more, but since the game itself isn't well optimized there's not much else I can do).
