I have a weird problem.
I build my own computer, with this specs:
AMD FX-4100 3,6ghz
MSI GeForce GTX 650 Ti Power Edition
Samsung 840 Pro SSD 128 gb
WD Elements HDD 1tb
KingstonKVR1333D3N9/4G (valueram) 8gb (2x4)
Motherboard Asus M5A78L-M LE
I can't play any game without lag. Even not simple games!
I updated all my drivers, but the problem is still there.
What should be the problem?
(I am thinking it is the processor, because some said it's not really a good gaming processor and actually a dual core.
I tried everything, even tried other monitors than my own Acer AL1916, but without any luck.
Yes I see i've forgotten my psu:
Cooler Master Extreme Power Plus 500W
I am playing Euro truck simulator 2, Midtown Madness 2, Mafia 2 and GTA IV (not simple), all with lag.
Especially when I'm driving a car. If I walk in for example GTA IV I don't notice any lag. I have a framerate of about 60 in GTA.
Here is my benchmark for GTA IV:
Average FPS: 64.12
Duration: 37.13 sec
CPU Usage: 68%
System memory usage: 42%
Video memory usage: 90%
Video Mode: 1280 x 1024 (60 Hz)
Texture Quality: High
Shadow Quality: Medium
Reflection Resolution: High
Water Quality: High
Texture Filter Quality: Anisotropic x4
Night Shadows: Off
View Distance: 25
Detail Distance: 31
Microsoft Windows 7 Home Premium
Service Pack 1
Video Adapter: NVIDIA GeForce GTX 650 Ti
Video Driver version: 310.90
Audio Adapter: Digitale audio (S/PDIF) (High Definition Audio-apparaat)
AMD FX™-4100 Quad-Core Processor
If GTA is the game you're looking at you're getting around what I'd expect with that PC. GTA 4 isn't what I'd call a well optimized game, and speeding around in a car forces your PC to render more stuff that much faster than walking, which is why you're having issues in the car. If you see your GPU's ram you're getting up there for what it can handle.
As for Midtown Madness 2, are you running windows 8 by chance? I've seen that it has had issues with others in the past.
I run ETS2 on high settings, also with a bit lag.
But I have to say, I've tried to run GTA IV on medium and even on low, but it still lags.
I can hardly imagine that the GPU is the problem, because it should run on low settings then.
I had a Geforce 9800 GT 1gb a few years ago, which seems to perform less than the GTX 650 Ti, which I have now.
The strange thing is, that this games ran smoothly on the 9800 GT. I had a Phenom II X3 then.
My system will lag on GTA 4, it's just not an optimized game. (My PC being an overclocked i7-930, a 7970 OCed and 12GB of ram). Some PC's just seem to respond better with it. You can even see your CPU is working less on GTA than your GPU which is hitting close to it's ram's cap.
As for ETS2 with a 'bit of lag'? Most games will lag sometimes when loading and such.
I also saw a AMD Phenom II X6 1045t, which is compatible with my motherboard. Which is better: the FX-6300 or the Phenom X6 1045t. The X4 965 is not compatible. I already had this but my motherboard couldn't handle it, so I returned that one, and got the FX-4100 from my computer store.
Nearly one month later...
I replaced the PSU with the Corsair CX430 (because my previous psu has less amperes than my gpu needs), wich is better than the one i had. But this didn't solve my lag problem, so it must be my cpu. I am doubting between replacing my cpu with a AMD Phenom X6 1045T 2.7ghz or the AMD Phenom X4 960T BE 3.0ghz. Wich one would you suggest? I don't want to overclock, because i'm not very good in BIOS stuff. Although unlocking cores of the 960t should be very easy on my mobo, the Asus M5A78L M-LE. (can I unlock the 2 disabled cores with the stock cooler that comes with the 960t? And if I can, would unlocking cores affect te clock speed?)
