The game normally runs at about 50 FPS for me, but when I hold down a keyboard key it changes to about 60 FPS (pressing keys increases FPS by 2 - 4 for a second or two).

Wait a minute; are we talking about a difference in FPS from 40 or 50 to 60? When this issue was first presented to me on IRC, it was in the terms "sometime its like 10fps cant even run".

Trying to solve a problem where the client lags to the point of unusability would be a completely different thing from simply increasing the FPS, not least because the usual FPS of 50 simply is a result of the client limiting its own framerate to 50 in order to preserve general system resources.

So let's be clear about what the issue actually is to begin with, please. :)

It is true that the FPS generally goes up when handling input events, but that's more like a bug, since the wait loop is interrupted by new input events.

Loftar, the hold key fps increase is just an extra info. It becomes *unplayable* for me, and when it does I use the hold key to play. I even made a autohotkey macro that holds my W button so I can play in this situtation. 

Also, sometimes eventhough it says 50fps its like 10 fps and you cant even move hardly. I've played first person shooter games for 10 years competitively so believe me when I say I can feel the difference in fps, there is something wrong here.

That sounds a bit interesting. If the client says 50 FPS, then it literally means that it has actively drawn 50 frames during the last second. If, in spite of that, you have only seen some 10 or less different frames during that period, then I think that has to mean that there's something else on your system preventing those frames to be emitted to the monitor. Do you have any weird programs or driver installed or some system graphics settings that could cause such interference?

Oh, and if that is not the case; since you can see the client's FPS meter, then that means that you're capable of turning on the client's debug mode. I would suggest, then, that you also turn on the profiling mode and use it to check just what it is that's taking time. With profiling mode on, use the ` and ~ keys to open the global and the mapview profiles, respectively.

I'm just using fraps / MSI Afterburner to see the fps of the client. I dont have the console active but I can open the MV and Glob graphs, take some screenshots and post the links. I have nothing weired installed and all my drivers are up to date. I'm not having problems with any other games, and I recently reinstalled windows 7 just for the problem but nothing has changed.

Here is the images, they are kinda low quality since I uploaded to imgur first time. You can check the description of the each image for more info. When I hold any key, you can see the change in graph

I do see that the peak frame in the glob profile you posted says about 25 ms, which really isn't a lot and couldn't be causing a drop below 40 FPS, at least, so there has to be something outside the client causing some kind of weird interference.

I do, however, seem to recall that some people using FRAPS to capture footage from the client reported similar problems, so it could actually be some weird interaction between the client and FRAPS. Have you tried turning it off to see if that makes a difference?

I dont use fraps, I just use it to show you fps and see myself. Everything aside, is it even normal to get 40-50 fps with a computer such as mine?

Ah, but even if you're not recording, it's clearly doing something with the client in order to monitor the FPS.

Well, as I stated, the client limits itself to 50 FPS, so you wouldn't get more than that. :)

Well I fixed my problem. First of all, obviously Salem just does not use enough of my GPU. Actually, my GPU just does not think it is needed to perform for Salem. What I did to fix this was I maxed out everything possible from the catalyst center AA 16x, Anisotropic Filtering 16x, HQ Mipmap, Super-sample AA and a predefined CrossFireX profile (3dMark Demo).

After those settings, when I run Salem it stats as before with looks like low fps but after 20-25 seconds the both of the GPU use increases from %5 to %60-70 and I have a smoother gameplay. Still, its not the perfect performance but at least its playable unless I open another client which causes %100 GPU use and my card cant handle it. At the moment, my fps is around 40-45 (previously it was 50-53) but its way smoother so I'm not sure if it is about fps at all but I can assure you that you have a serious performance issues and everybody I have met/asked has a *meh* computer and they dont mind playing with low performance since its not a fast paced game.

PS : I can assure you that this is not a personal problem, I asked my friends with same or better configurations to run the game and they all experience the performance issue.

That does seem exceedingly weird. :)

I'm sorry to say that I have no clue what that means.

Its just a problem about my gpu actually. They update the driver according to games and softwares but a java game is not on their list I guess. So I left an email to them already. What I'm doing basicly is that forcing my gpu to work at 80% and this is only to play Salem. At least works for now ^^
