I'm running a trading platform (TD Ameritrade's thinkorswim, "TOS"), and there's a bit of lag in this Java-based app. Examples of lag/choppiness:
machine specs:
Dell XPS 8700 mid-tower
Intel Core i7-4770 @ 3.40 GHz
32gb DDR3 1600Mhz
AMD Radeon R9 270 with 2GB vRAM
Windows 7 SP1, 64-bit
I have 4 monitors connected to the R9 270 graphics card (integrated graphics are disabled in BIOS).
Here are a couple of snapshots of Windows Resource Monitor, Task Mgr, and GPU-Z, taken (1) before launching TOS and (2) with TOS running.
Before launching TOS:
TOS running full bore, with lots of charts updating with streaming data, and streaming video playing:
To my inexperienced eye:
- I can out-type the characters appearing on the screen in TOS chat window
- streaming video in TOS is very slightly choppy, but audio is fine
- TOS pop-up windows are slow to appear and disappear

To my inexperienced eye:
- CPU is not the bottleneck
- system RAM is not the bottleneck
- unsure about graphics card. GPU load is only 28%, but memory used seems high relative to the 2GB available, with 1443 MB used/dedicated and 326 MB used/dynamic. Not much spare capacity at this snapshot, which I guess means that there are probably instances where all the vRAM is used and I guess excess is offloaded to system RAM and slows things down?
