I'm doing a remote desktop to my computer...I'm almost positive that after a reboot and logging in locally this is happening but I'll have to double check when I get home. Sorry.

2) Message boards : Questions and problems : No Useable GPUs found - NVIDIA - Windows - Not a service! (Message 51309) Posted 14 Nov 2013 by MysticRyuujin Post: I see a ton of posts about AMD/ATI cards not being found but nothing for NVIDIA. I also see some posts for Linux but not Windows (except those running it as a service...) I am NOT running it as a service. GPUs are NVIDIA GTX770s and the current driver is 331.65. I've had this issue off and on for a while now. Sometimes it works, sometimes it doesn't...I've tried closing / stopping and restarting but that doesn't help either. 11/14/2013 9:15:26 AM | | Starting BOINC client version 7.2.28 for windows_x86_64 11/14/2013 9:15:26 AM | | log flags: file_xfer, sched_ops, task 11/14/2013 9:15:26 AM | | Libraries: libcurl/7.25.0 OpenSSL/1.0.1 zlib/1.2.6 11/14/2013 9:15:26 AM | | Data directory: C:\ProgramData\BOINC 11/14/2013 9:15:26 AM | | Running under account chase 11/14/2013 9:15:26 AM | | No usable GPUs found 11/14/2013 9:15:26 AM | | Host name: WS 11/14/2013 9:15:26 AM | | Processor: 8 GenuineIntel Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz [Family 6 Model 60 Stepping 3] 11/14/2013 9:15:26 AM | | Processor features: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush acpi mmx fxsr sse sse2 ss htt tm pni ssse3 fma cx16 sse4_1 sse4_2 movebe popcnt aes syscall nx lm tm2 pbe 11/14/2013 9:15:26 AM | | OS: Microsoft Windows 8.1: Professional x64 Edition, (06.03.9600.00) 11/14/2013 9:15:26 AM | | Memory: 31.94 GB physical, 63.94 GB virtual 11/14/2013 9:15:26 AM | | Disk: 476.89 GB total, 311.16 GB free 11/14/2013 9:15:26 AM | | Local time is UTC +9 hours 11/14/2013 9:15:26 AM | | Config: don't use GPUs while BatmanOrigins.exe is running 11/14/2013 9:15:26 AM | | Reading preferences override file 11/14/2013 9:15:26 AM | | Preferences: 11/14/2013 9:15:26 AM | | max memory usage when active: 16350.83MB 11/14/2013 9:15:26 AM | | max memory usage when idle: 29431.49MB 11/14/2013 9:15:26 AM | | max disk usage: 311.31GB 11/14/2013 9:15:26 AM | | (to change preferences, visit a project web site or select Preferences in the Manager) 11/14/2013 9:15:26 AM | | Not using a proxy 11/14/2013 9:15:27 AM | | GPUs have become unusable; disabling tasks

3) Message boards : BOINC client : Windows 8.1 x64 Pro and Hyper-V (Message 51211) Posted 8 Nov 2013 by MysticRyuujin Post: So it looks like the issue is that the hypervisor that my OS is running on is giving the host OS priority over the VMs. That makes sense but it also sucks because I don't think running BOINC inside a VM is going to allow it access to my GPUs for crunching :( Not sure if RemoteFX would even be capable of assisting with that issue. I assume not. I may just have to live with it. But I'd still like to hear what the BOINC developer has to say about it. As for what happens with idle/loaded nothing really changes. BOINC on = terrible performance. BOINC off = Works fine. When I use stress on the Ubuntu VMs the virtual CPU spikes to 100% but the overall performance remains relatively the same and I don't see a major change in the VMWP (it's only got 1 vCPU on a logical 8 core system).

5) Message boards : BOINC client : Windows 8.1 x64 Pro and Hyper-V (Message 51044) Posted 27 Oct 2013 by MysticRyuujin Post: Just for giggles I turned off Dynamic Memory but it had no effect. Same issue.

6) Message boards : BOINC client : Windows 8.1 x64 Pro and Hyper-V (Message 51043) Posted 27 Oct 2013 by MysticRyuujin Post: The number of VMs running is irrelevant, I currently have 4 VMs (3 Generation 1, and 1 Generation 2). Ubuntu 13.10, Windows XP, Windows 7 x64 and Windows Server 2012 R2 being the Generation 2 VM. The problem is with the Generation 1 VMs. Generation 2 VMs don't appear to suffer from this issue. So if only Server 2012 R2 is running it's fine but as soon as I start any of the Generation 1 VMs I get this issue. Each VM uses dynamic memory, from 1-4GB. My host memory isn't even 50% used...ever. The generation 1 VMs sit at about 1-2GB and the Generation 2 sits at about 2GB. So even if all of the VMs were maxed I'd be at 50% but they're not maxing out anyway. Doesn't matter how many cores I assign. 1 CPU each, 2 CPU each, same behavior. And yes, the VMs are doing nothing. They are sitting there, not really doing much right now as this is a fresh install and I haven't gotten around to doing anything on them because of the performance issues with BOINC. So their CPU (and the VMPC process) uses is like 0-2% max at any given time but as soon as I start BOINC the VMPC process jumps to 1/9th of 100% (8 BOINC apps + VMPC). If I change BOINC to "Use at most 50% CPU time" there is no difference. The usage percent drops in half obviously but the VMWP usage = the same usage of the other 8 BOINC processes. If I change BOINC to "On multiprocessor systems use at most 50% of the processors there is no difference. VMWP = the same usage of the other 4 BOINC processes. The only project I run is World Community Grid the current processes appear to be fight aids at home? (fahv_vina_7.06) & (fahv_vina_prod_64) Thanks!

Basically unusable. When I look at the task manager the "Virtual Machine Worker Process" is either using almost no CPU (BOINC OFF) or using an even amount of CPU as the other BOINC processes when BOINC is ON. It's not a hardware bottleneck: ASUS Z87-WS Motherboard Core i7-4770K 32GB RAM 2x Samsung 840 Pros (OS) 4x Western Digital Red 1TB drives - RAID10 (Data) 2x GTX 770s 2x Gigabit NICs in LACP team Snooze GPU doesn't affect anything. Has anyone else experienced this? It's a clean Windows 8.1 install, not an upgrade.
