Dungeon Defenders lag!

Ok so i get on DD and play for a while right. After like a hour or so of playing my fps starts to drop until about 10 or it crashes. The sound skips too. But its weird that when i start its all fine 60 fps no lag even on a demanding map or wave.  

I tihnk it may be my processor but what do you guys think? 

THANKS

Check if you have some background apps running or not.
Also check if you have this setting (from the config launcher) enabled or not -- "Don't use multi-threaded renderer"
If the setting is un-ticked, tick it and see if the game crashes or not. 
From in-game settings disable a setting named -- "Dynamic Tower Lights" as well.

Still lag, but only now takes hour and a half!!

What processor and graphics card do you have?  Could be an issue of throttling if your proc or graphics are getting too hot.  Does it do that on any other games?

My processor is a AMD FX-6100  Six-Core processor, Graphics card is a  AMD Radeon HD 7700 series.     I might be i will check the fans and everything.  No all the other games are doing just fine.

I don't know the model numbers well, is your CPU a socket AM4 chip (it would be a new CPU, the same socket that s upports AMD Ryzen)? Because I'm having a similar issue in DD2, and possibly other UE3 games.

I have that exact same CPU(although overclocked @3.9GHz), but a different GPU(GTX970). Game works fine for me on that processor.
If you say the issue is related to just this game, then you could try doing file re-validation and/or re-installation of the game(make sure to back it up first). Use a hardware monitor software like HWMonitor or MSI AfterBurner and see what are the CPU/GFX temps, and how much RAM/CPU it is consuming.

FX-6100 is an older AM3 socket CPU, unrelated to the latest AMD AM4 based CPUs.

When i play it i do have something in the top right telling me how much ram,cpu, and disk. The average % when i play dd for the ram is 42% for the cpu its about 30-40%. I reinstalled it and re-vad. Temp is only 45 C. its still doing it after all of that wtf. Maybe something is stacking up like a loop and making it lag a lot idk.

What resolution are you playing it at, and what sort of GPU settings are you running with the NVIDIA software? Forcing high-quality graphics settings can cause lag issues.

1920 x 1080 i tried lowering it, it doesn't fix it. I have a AMD software and im sure thats not the problem because every other game works just fine. Also i played Dungeon defenders  before and this NEVER Happen. But i did switch out the hard dirve with a better one, but i don't think thats the case.

ok so i think i found the problem i think its the ram building up untill it crashes.

You may be running a driver set for that card that is too new for the card itself to be running efficiently, which is common for old graphics cards and newer drivers for older games.  It's not very likely a memory leak unless one of your own ram modules has been damaged or overheated too much, else it would be a memory leak the rest of us would be experiencing presently. 

You might want to try rolling your drivers back to something a bit older and see if that remedies the matter. There's another potential issue where you're maxing out your GPU ram running other programs in the background whilst playing, since your particular card only has 1GB to it's name, which is optimal for DD, but if it's capped out from other processes then DD tends to slump in performance.

Alright i couldnt roll back the driver but i could update them but stil not working.
