For reference, I just ran the Ensemble8 demo on a Windows 10 laptop with
a 200% scaled HiDPI screen (3000x2000) with integrated Intel HD Graphics

The laptop also has an embedded nVidia 900 series GPU, but I need to

Hi Jim,
I have experimented with all those options with the following results:
1. Turning on verbose proves hardware acceleration is being used.
2. Increasing texture size and fiddling with the amount of VRAM has no
effect on performance.
3. Turning off Hi DPI changes the appearance of the app (i
Other things to try:

-Dprism.maxTextureSize=8192 (mentioned before - increases max texture

I doubt it would be simply a "number of pixels" issue. I don't have a
4K monitor, but I've run it on some HiDPI monitors that keep up just
fine with much more modest hardware.
There are a couple of possible things that may get in the way:
- Our max texture size is 4096x4096 which should be la
Hi Jim,
I had Windows 10 on my previous machine and my wife's low-end PC is also
running Win10 and the same version of Java.
But I have what is supposed to be the fastest graphics card of all (GeForce GTX
Titan X) and she has a very basic card.
The only real difference is that she has a 22" mo
Have you tried running it with -Dprism.verbose=true flag?
It should provide some debug output.

It should be supported. Which version of Windows were you using before?
We've supported HiDPI on Windows since JDK8u60 on all supported
versions of Windows...

Sadly JavaFX still performs like a one-legged dog dragging a cannon ball on a
chain.
All other 3D apps, games etc. perform blindingly fast as I would expect.

That's curious. SLI is designed specifically with gamers in mind!
I'll investigating running without SLI and report back.

I am using Java 8u66 and performance is really poor.

Hi-DPI is supported on Windows, assuming you have 8u60 or later (better
8u66 or later so a ComboBox doesn't freeze the application!). On my Dell
XPS-15 with Windows 10 and 4K displays JavaFX also uses hardware
acceleration, in this case with the Intel 4600 integrated GPU.
However, this causes
