Hey all,

I still get the low FPS bug regularly - probably several times a week but since the last patch I've had it more than once a session including, unusually, one occasion of it happening on the first game I played that session.

Usually it happens when I've had the client open for a longer period of time - more than a few hours. The only fix is to restart the PC, just deleting the shaders folder doesn't fix it.

Does anyone else get this? Are there any effective workarounds that don't require a restart?

It just seems so weird to me because closing and reopening the game doesn't fix it - I would have thought a memory leak would be resolved by doing that.

Need more information. Almost anything could be affecting the game that could be causing low FPS, such as programs popping up and utilizing all of the avail CPU resources, choking MWO to either/both CPU/GPU throttling down.

Info needed would be dxdiag, just from the top down to and including video/sound card info.

Are you running Process Explorer/Task manager and checking to see if System Idle Process takes a dunk?

Any programs to monitor CPU/GPU temps and current data on speeds?

Are both Power Options and Power management options for CPU/GPU set to Best/Max performance?

And when you say long sessions, how long, time-wise and how many drops?

*Running the MWO repair tool fixes the problem - so is there anything the tool fixes that I can replicate without running it? Another folder besides shaders to delete that I don't know about?

I'm not monitoring temps at all but I have checked task manager when it happens and couldn't spot anything unusual. No processes using high CPU, performance graph doesnt show ram or cpu usage peaking. My dxdiag info is here: https://dl.dropboxus...5287/DxDiag.txt

Power plan is set to Balanced - could that be a problem? I have to confess I don't know much about the power settings.

*Most of the time I get quite playable FPS - 45-50 - it's just after the client is left open for a while it will sometimes start running at about 10-14fps and then it continues doing that until restarting, which usually but not always fixes it, or running the repair tool. It can happen after running anywhere from several hours to overnight.

I don't have this but until I use night vision or thermal in extreme close quarters fire fights, FPS drop to about 5 and I end up fighting in a snow storm in dark screen on RCN. Nothing has changed apart from last patch with my system.

As soon as I turn the vision off, my FPS come back up

performance that varies due to graphics mode changes (such as night vision which toggles a shader) hints to a GPU bottleneck--which GPU did you have this problem on?

as for GPU temperatures, that could cause problems, though I would imagine if the problem is specific to this game and not others then perhaps it's somehow our fault (so more info would be good if that's the case)--I made the mistake of building a 100% fanless gaming pc a few years ago... never again!

as for running the repair tool helping performance--if the tool actually found corrupt data then perhaps that could account for it, but if it didn't find any errors then it wouldn't cause a difference other than through coincidence.

as for the original post, I am assuming it is alluding to an elusive "4fps bug" that we've seen RARELY happen with no consistent repro case (so it's hard for us to track down if we can't reliably reproduce it in the dev environment) If that's the case, and for some reason you experience it consistently then some info regarding your system spec as well as your in game graphics options settings would be useful for us.

thanks and sorry for not having more frames for you when you need them!
