jasonnoguchi 11 Posted December 3, 2009 Ok, one thread dedicated only for video memory... Can someone shed light on what all that setting for video memory mean? Share this post Link to post Share on other sites
Defunkt 431 Posted December 3, 2009 For your card (HD4870 1GB same as mine) you should first try 'Default'. Share this post Link to post Share on other sites
jasonnoguchi 11 Posted December 3, 2009 Thanks for responding Defunkt. What does "Default" mean then? I have been playing with it at Highest and I get random stuttering when near the warehouse and also everytime I respawn in armoury games. Share this post Link to post Share on other sites
Defunkt 431 Posted December 3, 2009 There's a thread around somewhere that explained that every option other than Default is actually a legacy setting and refers to a specific amount less than 1GB. Default auto-detects and in the majority of cases this will be correct, to make sure check the localVRAM entry in your ArmA.cfg, IIRC this is what it has detected, mine is 1073741824 (1GB'ish).

jasonnoguchi 11 Posted December 3, 2009 Tried setting to "Default" and immediately get spikes when moving. I then switched immediately to "Very High" again and the spike disappeared. any hint what is going on? My localvram is exactly as yours. Share this post Link to post Share on other sites
Defunkt 431 Posted December 3, 2009 Sorry, dunno, I got the opposite, having used Very High for a while I then saw an immediate improvement after switching to Default. Share this post Link to post Share on other sites
kklownboy 43 Posted December 3, 2009 Tried setting to "Default" and immediately get spikes when moving. I then switched immediately to "Very High" again and the spike disappeared. any hint what is going on?My localvram is exactly as yours. yeah you get spikes on default?But thats why we have options to find the one that works, Default should be the amount you have but VH seems to work instead. I use Default, its better with CFX and my 2GB of VRAM (no strobing or dark flicker), but VH seems better on spiking/artifacts..( which seem to have started up with 9.10,9.11 Cats for me. Small ones easy to flush, do it twice it seems to go away for alongtime,Hours)Its how the game and the DX and the Driver use the framebuffers of your vidcard.

jw custom 56 Posted December 3, 2009 I have 1GB VR and i got Video memory set to High. If i set it on Default i get CTD's at random times. Share this post Link to post Share on other sites

It occurred to me that possibly what happened here is that switching to Default (and using all available video memory) may have exposed a HDD bottleneck. Your transfer speed from disk may not be sufficient to service all that video memory. Share this post Link to post Share on other sites

Your transfer speed from disk may not be sufficient to service all that video memory. I think you may be right there as I have a pretty crappy jmicron HDD SATA2...hahahahah . Which means that with a crappy HDD, i cannot push my GPU to the max? :((( Share this post Link to post Share on other sites
Daykeras 10 Posted December 5, 2009 Where can I find this "Default" video memory setting. I only see Normal and Low Share this post Link to post Share on other sites
pj[cz] 2 Posted December 6, 2009 it has been said numerous times in other threads, i dont know if i can reproduce it exactly but should be something like this: high=256mb vm, very high=512mb vm, default - the game tries to determine the amount you actually have and use it. For my gtx260 with 896Vram it works as i get the best results by using default... Share this post Link to post Share on other sites
bushlurker 46 Posted December 7, 2009 This was a post about video memory... not an official guideline - more a "best guess so far"... The thread as a whole was about a graphical issue, but ended being a discussion about video memory so its worth looking through... B Share this post Link to post Share on other sites
