Rabid GTA Gamer Posted March 4, 2011 Share Posted March 4, 2011 (edited) Here's the gory details of what I see when playing EFLC/GTA4... System Specs: CPU: Intel Core I5 2500K @ ~4GHZ (Sandy Bridge) GPU: (1-2X) Sapphire HD 6950 2GB RAM: 8GB Mushkin Silverline DDR3 (1333) SSD: Mushkin Callisto Deluxe 240GB PSU: Corsair 750 Watt (Non-Modular) MOBO: Asus P8P67 Pro CASE: Antec 1200 V3 (With USB 3.0) OS: Windows 7 X64 SP1 Drivers: Latest From AMD/ATI Website (11.2 - Feb 15 2011) Games: EFLC Disc Version (Latest patch) GTA4 Disk Version (Latest patch) This problem is only when it rains, everything else seems normal. (Except Performance) So yeah, the game play tolerably with a single video card with FPS generally around 55... You're thinking, that's great, now quite whining! BUT this is with all settings on "High" and all the sliders at 25-30. OK, but when I move the sliders up any higher, FPS doesn't drop that much but it'll freeze for a second when moving the camera around... With the crossfire setup, I have to use the command-line argument to let me use decent settings since it claims that two video cards are less powerful than one! I would like to max it with crossfire, which is the reason I bought 2 cards... I've disabled page file, etc. It's not even running at 1080p for goodness sake! The green rain is NOT a hardware issue! (I tested my second card straight out of the box before any OC, etc) Also when in crossfire with everything maxed, I get "micro-stutter?" or something like that... So feed me solutions that actually have a chance of working... Compatibility Mode? Command-Line Arguments? Overclocking the RAM? (CPU isn't maxed while playing) Special setting to force via RadeonPro or ATI Tray Tools? Edited March 4, 2011 by Rabid GTA Gamer Link to comment Share on other sites More sharing options...
shahmen Posted March 4, 2011 Share Posted March 4, 2011 Try to run it in safe mode. Link to comment Share on other sites More sharing options...
Rabid GTA Gamer Posted March 4, 2011 Author Share Posted March 4, 2011 (edited) Try to run it in safe mode. And that would fix what? This has persisted through a clean install of windows 7 and new drivers, etc... Experienced users please! Edit: Running in safe mode is not an option. New rig, old game, no compromise...

mkey82 Posted March 4, 2011 Share Posted March 4, 2011 The game has bad CF support, don't use it. This green rain happens on single card or with CF? Various people had various rare graphical glitches and I haven't seen any of those resolved. Link to comment Share on other sites More sharing options...

Various people had various rare graphical glitches and I haven't seen any of those resolved. Single Card straight out of the box has green rain. True, AMD has given no response whatsoever to my reports. This same issue is also reported for the 6970 cards on other forums... So yeah, one OR two cards show the same behavior. I read somewhere how someone got theirs to work tolerably in crossfire, but can't remember where... (some other forum, with older cards) So this setup has 4GB GDDR5 Video RAM and the game plays badly. I've tried forcing various things like tripple buffering without substantial results... So even with one card, maxing (or even going above 30 in the sliders) makes it almost unplayable. With a card of this strength, this must mean that there's some kind of a conflict somewhere. (most likely crappy coding in the game itself, though it's not maxing my CPU ) Link to comment Share on other sites More sharing options...
mkey82 Posted March 4, 2011 Share Posted March 4, 2011 VRAM does not stack up, two 2GB cards will provide 2GB VRAM, not 4. Link to comment Share on other sites More sharing options...
Rabid GTA Gamer Posted March 4, 2011 Author Share Posted March 4, 2011 (edited) VRAM does not stack up, two 2GB cards will provide 2GB VRAM, not 4. Strange, but mine does... Note that in crossfire, i have to use the command-line just to go above the lowest settings possible... No matter, I still have a metric ton of VRAM!

mkey82 Posted March 5, 2011 Share Posted March 5, 2011 VRAM does not stack up. Which commandlines are you using? Link to comment Share on other sites More sharing options...
Rabid GTA Gamer Posted March 5, 2011 Author Share Posted March 5, 2011 Right now, the -norestrictions one to be able to select decent settings... Tried others, but no improvements... One commandline and all driver default settings... Getting the green rain fixed in the next drivers seems unlikely, so anyone who is experiencing this issue should also report it. IF ENOUGH people complain, it MIGHT get fixed... For example, would the memrestrict command make sense for a system that has a lot of VRAM and a lot of ordinary RAM? It never uses THAT much of the available resources!? Link to comment Share on other sites More sharing options...
Rabid GTA Gamer Posted March 6, 2011 Author Share Posted March 6, 2011 (edited) My Benchmark: Statistics Average FPS: 46.62 Duration: 32.95 sec CPU Usage: 65% System memory usage: 32% Video memory usage: 19% Graphics Settings Video Mode: 1680 x 1050 (60 Hz) Texture Quality: High Shadow Quality: High Reflection Resolution: High Water Quality: High Texture Filter Quality: Anisotropic x8 Night Shadows: High View Distance: 50 Detail Distance: 50 Hardware Microsoft Windows 7 Home Premium Service Pack 1 Video Adapter: AMD Radeon HD 6900 Series Video Driver version: 8.17.10.1065 Audio Adapter: Speakers (High Definition Audio Device) Intel® Core i5-2500K CPU @ 3.30GHz March 8 2011 Edit: By forcing "AFR Friendly D3D" in RadeonPro, it now runs smoothly... However doing that seems to cause some flickering when exiting the safehouse, and rare other times. FPS is bad, but it IS maxed out... However RadeonPro reveals that the cards aren't even working that hard... Less than 50% usage, though FPS occasionally drops down to 20 but remains very playable. If I didn't have the SSD, I'd suspect HDD speeds. So the question changes to this one: What can i do to make it use the cards more, and thus have better FPS. I've tried triple buffering with no noticeable results. The low FPS is ONLY outside while doing extreme stuff. Thoughts from GTA4 PC veterans?
