Multi-windows web browing slows down the system at max resolution 1360 mode.
I thought something wrong with computer. I changed back to SVGA 1024 mode, and the speed is back to normal without any hestitation. I guess there is no way to run max LED 1360 mode without upgrading the system.
That shouldn't happen.
The speed should not change that dramatically.
Check the Event Viewer, to see if the video driver has a problem
and is reporting errors. It sounds like hardware acceleration
is becoming disabled for some reason.
Also check Device Manager, look at the video card entry ("Display Adapters")
and see if the drivers loaded for the video card are reasonable. My
card is NVidia powered, and there are at least a dozen driver files
with names like "nvapi.dll" and "nv4_disp.dll".
When I loaded Windows 8 on an FX5200, there was no video driver, and
that one stays stuck at 1024x768, no matter what kind of display
is connected. And the only video card driver files, are a few Microsoft
fallback files. So that would be a case of "missing drivers". That
doesn't sound like your problem, but I would check.
The DirectX software provides DXDIAG program. Go to Start : Run
and enter "dxdiag.exe" and run it. Under the Display tab, there
are two test buttons. "Test DirectDraw" for 2D testing and
"Test Direct3D" for testing 3D operations. Note that not
all OS versions, is the DXDIAG the same. The latest OSes, the
DXDIAG just isn't as good. You want to at least test DirectDraw
while at 1360, and see if the test "throws error dialogs" and
reports some kind of problem. The test itself (what it draws on
the screen), is pretty useless. What we're checking for here,
is "complaints" from the test software.
And if you can't figure out your video from Device Manager (devmgmt.msc),
you can also use GPU-Z for a summary.

This is the last version I got.

This is my video card in GPU-Z. The video card is old.
As a result, no tick boxes at the bottom are ticked. Not a
big deal. The info here, tells you a bit about what kind of
hardware is involved. My memory size of 512MB, which is on
the video card itself. It's not a shared memory.

I just found a 2D benchmark here. You can give this a try.

The program seems to test a fixed number of objects, so
the runtime varies with slowness of machine. It could
take two to ten minutes. I don't recommend sitting in
front of the computer while it's running (especially if
you're epileptic). Just wait for the summary dialog to appear.
The runtime of the test is entirely too long.
These are two test runs I did, showing the summary box.

What I liked about my result, is it shows the VM somehow
hooks into native rendering for Text and Arc/Ellipse, and
maybe Stretching. Kinda weird.
You can run the test on your two screen resolutions,
and see if there is a difference or not.
