    Hi, I've been fighting a fps drop for weeks now. It started in WoW, where my fps go from 60 (capped due to v-sync) to 5. After going through a few different OS's and a few different video card drivers, I am currently running Win 7 with Dox 180.70 and BIOS 9c.12.00. I had given up on WoW (assuming it was just poor coding in WoW) and was playing LOTRO tonight. Again, I got the same fps drop. First, I popped up the resource manager to check cpu/hdd/mem usage. I saw the CPU at 33% maximum frequency associated with the fps drops. Then, I turned on HWMonitor to check temps while the fps dropped, and played the game in windowed mode. I saw CPU maximum frequency at ~89%, no longer changing with fps drops. I did find my gpu is maxing at about 108 C after about 5 minutes of playing O.O. Idle gpu temp finally comes down to 51 C as a minimum. CPU maxes at 68 C and idles at 34 C.

    So, is my gpu busted? If the gpu is bad, is this the sort of thing I can replace myself?

    Sorry if the story is a little convoluted,
    Jahajazz

    To easy man, For some reason Ive seen alot of this lately, your GPU is getting too hot and throttling down to save itself. The FPS drop you experience is the GPU lowering its voltage and clocks to reduce heat.

    Here is what you need to do, blow/clean out the vents on your computer. Verify that the GPU fan is working, its the vent on the left side when using the computer. If these two things are good then Im afraid your next step is to disassemble your laptop and apply new thermal compound to the GPU heat sink. Its not too hard and there is a disassemble guide on this thread somewhere. Good luck

    I play LOTRO as well, though not on Windows7 currently (as it was giving me blackscreens out of nowhere after varying times of playing), but on Vista.
    As Infiniteone correctly says, clean your fans (I use an airspray) depending on where you live you have to do this often. I have quite some dust in my flat (living in the city with constantly open windows) and usually when playing a lot, clean out the fans every 1-2 weeks. Sounds a lot, but if you play a lot, the fans work a lot, suck a lot of air through the system and thus gather a lot more dust as when you don't use the GPU so much.
    Also I elevated my FX by 2-3 cm (glued some small round things under the preinstalled "elevation nobs"), thus giving the fans more air flow, helps as well.
    If it is running hot a lot, it might also be due to the surface your notebook is placed on. Naturally don't put it on your lap while playing ;), but also a wooden surface is certainly not ideal, as wood stores the heat (that is coming out of the system), and thus theoretically speaking, your fans will suck up "preheated" air.

    Though I have a wooden surface my notebook is standing on, my GPU rarely goes above 65C (close to max LOTRO graphic settings, GPU on a balanced quality-performance setting, etc.). Well that is, if it is not 30C outside, as it is now, than the GPU also starts kind of "boiling", but didn't fail me as yours does.
    And I have the LOTRO FPS capped at 60, thus the machine doesn't have to do unnecessary extra work.

    Hope it helps.

    Ouch. Make sure the GPU fan is even running.

    Okay, I cleaned out as much dust as I could, and my gpu maxes at about 80C. Things are much better now, the game is actually playable. However, I am still experiencing fps dips. FPS stays at about 45-60, then drops to 15, then back again. To further diagnose this, I watched HWMonitor. I noticed 2 things; my TZS0 is spiking to 98C (I am aware this is much discussed issue), and that my CPU is downclocking severely. To fix this I decided to use RMClock, as I read that it can force the CPU not to downclock. I setup RMClock to use the Maximum performance setting while on AC power, and set Maximum performance to use p-state transitions and selected only 8.0x multiplier. Watching the RMClock monitor:

    The CPU is still downclocking to 848Mhz and using the 6.0x mulitplier while gaming. Is there any way I can force the CPU to not downclock?
