3D Gaming Performance and Efficiency Issues with RemoteFX

We want to find out if remoteFX can be used for remote gaming.

System spec:

Gigabyte X58, I7-930, 12GB RAM, 250G HD(system), 500G*2(2 VMs per HD), Nvidia Quadro FX4800, 100Mbit LAN

Windows Server 2008 R2 SP1(Host), Win7 Ultimate(VM), 275.14 Quadro driver for WinServer2008 R2

Already set the capture rate to high and image quality to low in group policy for each win7 VM.

We totally run 4 VMs, all can login win7 VM with remoteFX with no problem, Aero experience good, online Flash video works well.

Testing Crysis War-Head in 1024*768 and lowest image setting:

For 1 client, it gets average 30fps. But for 4 clients, we only get less than 20fps and hard to play, the game is not smooth and sometimes drop to less than 10fps. The GPU load is only around 60% monitored by GPU-Z.

Tesing NFS14 in 1024*768 and lowest image setting, it only get less than 15fps and very hard to play.

Tesing 3dmark06 in one VM, SM2.0 test score is 2000 but GPU load is over 70%, while it should be over 5000 in the host system.

It seems the 3D efficiency of remoteFX is not good, does the CPU or any other setup matter the performance and efficiency?

In essence, you server is perfectly suited for RemoteFX. But what clients are you using? Can you check the CPU load on the clients?

Client is Pentium Dual-Core E6700 @ 3.3GHz. CPU load is around 20% on the clients.

Can anybody answer my question, how is the 3D efficiency of RemoteFX, can it be used for remote 3D gaming?

Your configuration, as explained by Benny is really good but, take in mind that:

1. your hypervisor "eat" some of the raw power of your cpu for doing it's job, so consider a little overclock or upgrading your cpu for more power

2. with a quadro driver you don't have all nvidia's optimizations for every game because of the professionnal nature of the card, consider the use of a geforce or the new grid solution (2014).

3. don't hope to run crysis on a card (FX4800 ~= GTX 260) that never ran crysis at full specs for one computer on 4 VM at the same time even at low specs.

For test purposes don't hesitate to use "custommer" GPUs and have multiples cards to create a gaming rig for many players (something like a cloud gaming server).

So, to answer you, it can be used for remote and cloud gaming, but it's not designed to do that, (FPS gets some troubles with RDP and mice data) and you should consider to link with remotefx a gamepad to enhance the gaming experience and avoid many default of the gaming use of RFX.

So to make it short, consider more GPUs (same gpu x times), a bit more memory to keep something to hyperV and a little CPU boost to catch up with the host performances

Sorry for my bad english,

Best regards
