Need Support - Thunderbolt Motherboard (Gigabyte) LucidLogik shutter (680GTX)

[mattkidd]

Hey,

I recently decided I would build a gaming pc solely for playing the odd game on and to go alongside both my rMBP and Thunderbolt display.

The biggest obstacle with getting this solution to work was to buy a thunderbolt compatible motherboard. The Gigabyte Z77X-UP5 TH.

My understanding behind this was natively the Thunderbolt display would only run off the integrated graphics on the machine. (HD4000) and not the dedicated. The board however offered the feature (Virtu MVP) which is software that allows the dedicated graphics to be streamed (not a technical description) to the thunderbolt ports found on the motherboard. Allowing the monitor to be plugged into the motherboard and not the graphics card which does not support thunderbolt.

I have managed to successfully get everything setup with the thunderbolt display (all drivers and operation between both the HD400 and GTX680 graphics card)

Some games seem to work perfectly (FarCry 3, SimCity), however others (GTA,Skyrim etc..) seem to be shuttering terribly, which is not an fps issue)

What would be the best solution? Are there any alternative options? Should I replace the thunderbolt with a cinema and do any hubs exist yet to convert anything over?

Would appreciate any support with this!

Thank you

A CPU issue?

SimCity doesn't take much CPU or GPU by modern standards, probably run fine no matter what.
FarCry 3 is more GPU than CPU.

GTA4/Skyrim are heavy CPU users.

Hmm really? Im running an IvyBridge processor i5 35070k @ native 3.4Ghz and Boost: 3.8Ghz?

I will have a look into this but it appears to be smooth gameplay just graphical glitches for example GTA IV runs smoothly except when you're moving everything shutters/jumps around you.

Well, if it was my problem:

Test #1: plug my monitor into the dedicated graphics card... see how it plays.

If it runs fine, then it's not the GPU/CPU it's a Virtu problem.
Doesn't run fine, it's either GPU or CPU.

I agree, make sure everything runs fine in normal mode (1 video card to 1 display). Then we can look into what might be causing the other issue.

Can you list more specs on your system?

Great well I managed to borrow a friends monitor and plugged that into the graphics card directly. Works flawlessly, so it's definitely a problem with the thunderbolt. It seems as though the vsync goes insanely crazy. There have been reports of this with 680s but I'm not sure if this is just caused by the thunderbolt.

My specs
