[SOLVED] Weird anomaly with Graphics in CS:GO

[RAIN]

Hello.

About a week ago, I noticed that somehow my CS:GO was lagging (FPS going up and down).
I tried reisntalling graphics drivers, even reinstalled windows.
Now the weird thing is, i get much higher and stable FPS in windowed or fullscreen windowed mode, than i get in fullscreen mode. (250 FPS vs 190 FPS).
It wouldn't be much of an issue, but near smoke grenade it's respectively 27 FPS vs 80 FPS. Now playing with 27 FPS isn't really acceptable for me, nor is playing in fullscreen windowed mode since it has got some weird micro stuttering lags.

Now from what I have read, it should be the other way around, fullscreen should provide smoother gameplay.

Resolution I tried with fullscreen: 1024x768 with black bars
Windowed and fullscreen windowed also 1024x768
Vsync turned off in CS and AMD control panel.

My system:
Win 8.1 (64 bit)
i5-3230M
8gb RAM
Intel HD 4000 + AMD HD 7670M

sound slike throttling

use an aircompressor or cans of compressed air to clean its vents
and get a laptopt cooling pad

I took the laptop completely apart 3 days ago, cleaned vents, replaced thermal paste. Im watching CPU and GPU temps and they are perfectly fine while playing.
But the thing that gives me headace is why on earth windowed mode provides more FPS than fullscreen, same resolution.

Ok I found the weirdest solution. If anyone experiencing something similar, here's what you should try:
1. Launch CS:GO
2. Alt-Tab out of the game
3. Launch Task Manager, open Processes tab
4. Right click on csgo.exe - select Properties
5. Select Compability tab
6. Tick "Run this program in compability mode for:" I selected Windows 7
7. Tick "Run this program as an administrator"
8. Restart CS:GO

That only is needed if the app has issues running at all. Doing something like this will not effect overall game performance or FPS.

If you FPS is good and then all of a sudden drops down to single or very low double digits; that is usually CPU/GPU throttle issue, that occurs when either of these reaches a high enough temperature. In laptops this temperature is usually right around 90-95*C depending on the laptop and/or hardware specs.

And when u say "the temps are fine" are you monitoring them in real-time while CPU and/or GPU is under high loads, and with a graph type history so u can see the up/down dips during peak loads and such.

You should probably try with Triple Buffering & V-Sync enabled; as ridiculous FPS will more than likely resulting in higher temperatures by default, especially in Laptops.

As I said, I just replaced thermal paste, cleaned vents, I watched processor and graphics chip temperatures for 10 minutes as I was playing. CPU never reached even 80C, graphics barely 60C. Do you play with Vsync? How the hell can anyone play with that? Even with triple buffering, input lag is too high. Maybe u didn't notice, but problem was not about the computer's ability to run the game, but why playing in windowed mode provided much more stable FPS than fullscreen mode. Noone plays in windowed mode.. And "doing something like this" resolved the issue..
