Many thanks for your quick response Mario!
I tried Screen(‘Preference’,‘SkipSyncTests’, 2) but Psychtoolbox aborted when detecting the MS software renderer. I next tried adding Screen(‘Preference’, ‘ConserveVRAM’, 64); to prevent the abort, however after displaying the Psychtoolbox splash screen it errored out on the first texture, output below. It’s not a challenging render, so any suggestions would be gratefully received!
PTB-WARNING: Created onscreen window on screenid 0 will probably not be able to use GPU pageflipping for
PTB-WARNING: Screen(‘Flip’)! May cause tearing artifacts and unreliable or wrong visual stimulus onset timestamping!
PTB-WARNING: Could not bind wglChoosePixelFormat - Extension. Some features will be unavailable, e.g., Anti-Aliasing and high precision framebuffers.
PTB-WARNING: Created onscreen window on screenid 0 will probably not be able to use GPU pageflipping for
PTB-WARNING: Screen(‘Flip’)! May cause tearing artifacts and unreliable or wrong visual stimulus onset timestamping!
PTB-WARNING: Your graphics driver doesn’t allow me to control if bufferswaps should be synchronized to the vertical retrace!
PTB-WARNING: This can cause massive stimulus timing problems, failure of the sync tests and calibrations and severe visual tearing artifacts!
PTB-WARNING: Please update your display graphics driver as soon as possible to fix this and make sure this functionality is not disabled in
PTB-WARNING: the display settings control panel of your graphics card.
PTB-WARNING: If everything else fails, you can usually manually enable synchronization to vertical retrace somewhere in the display settings
PTB-WARNING: control panel of your machine.
PTB-WARNING: Seems that Microsofts OpenGL software renderer is active! This will likely cause miserable
PTB-WARNING: performance, lack of functionality and severe timing and synchronization problems.
PTB-WARNING: Most likely you do not have native OpenGL vendor supplied drivers (ICD’s) for your graphics hardware
PTB-WARNING: installed on your system.Many Windows machines (and especially Windows Vista) come without these preinstalled.
PTB-WARNING: Go to the webpage of your computer vendor or directly to the webpage of NVidia/AMD/ATI/3DLabs/Intel
PTB-WARNING: and make sure that you’ve download and install their latest driver for your graphics card.
PTB-WARNING: Other causes, after you’ve ruled out the above:
PTB-WARNING: Maybe you run at a too high display resolution, or the system is running out of ressources for some other reason.
PTB-WARNING: Another reason could be that you disabled hardware acceleration in the display settings panel: Make sure that
PTB-WARNING: in Display settings panel -> Settings -> Advanced -> Troubleshoot -> The hardware acceleration slider is
PTB-WARNING: set to ‘Full’ (rightmost position).
PTB-INFO: OpenGL-Renderer is Microsoft Corporation :: GDI Generic :: 1.1.0
PTB-INFO: VBL startline = 800 , VBL Endline = -1
PTB-INFO: Beamposition queries unsupported or defective on this system. Using basic timestamping as fallback.
PTB-INFO: Timestamps returned by Screen(‘Flip’) will be therefore less robust and accurate.
PTB-INFO: Measured monitor refresh interval from VBLsync = 0.000000 ms [inf Hz]. (0 valid samples taken, stddev=0.000000 ms.)
PTB-INFO: Small deviations between reported values are normal and no reason to worry.
PTB-WARNING: Your graphics hardware & driver doesn’t support OpenGL rectangle textures.
PTB-WARNING: This won’t affect the correctness or visual accuracy of image drawing, but it can significantly
PTB-WARNING: degrade performance/speed and increase memory consumption of images by up to a factor of 4!
PTB-WARNING: If you use a lot of image stimuli (DrawTexture, Offscreen windows, Stereo display, movies)
PTB-WARNING: and you are unhappy with the performance, then please upgrade your graphics driver and possibly
PTB-WARNING: your gfx hardware if you need higher performance…

PTB-ERROR: Texture creation failed or malfunctioned for a texture of requested size w x h = 128 x 128 texels
PTB-ERROR: and at least 4 bytes VRAM memory consumption per texel.
PTB-ERROR: Currently there are already 1 textures, offscreen windows, movies or proxies open.
PTB-ERROR: All these objects consume system memory and could lead to ressource shortage.
PTB-ERROR: My current (rough and probably way too low) estimate is that at least 0.000000 MB of memory are
PTB-ERROR: consumed for textures, offscreen windows and similar objects.
PTB-ERROR: Another cause of failure could be that your graphics hardware doesn’t have sufficient amounts of
PTB-ERROR: free VRAM memory. Try to reduce the precision and/or size of your texture image to the lowest
PTB-ERROR: acceptable setting for your purpose.
PTB-ERROR: Read the online help for Screen MakeTexture? or Screen OpenOffscreenWindow? for information
PTB-ERROR: about how to reduce the number of color channels and/or precision of the texture.
PTB-ERROR: It may also help to reduce general VRAM memory consumption:
PTB-ERROR: Reduce the display resolution to the smallest acceptable resolution or disable the 2nd
PTB-ERROR: display of a dual-display setup if it isn’t strictly needed for your study.
PTB-ERROR: Other than that you could upgrade to more powerful graphics hardware (more VRAM) or try to split
PTB-ERROR: your oversized image into multiple separate subimages and draw them sequentially to the screen.
PTB-ERROR: That way you’ll be able to draw larger images, albeit at drastically lowered performance and more
PTB-ERROR: coding hazzle.
