1 00:00:00,000 --> 00:00:03,720 Even if you've spent tons of money on a top-end graphics card, 2 00:00:04,420 --> 00:00:08,220 graphical artifacts can still be an unfortunate fact of life. 3 00:00:08,720 --> 00:00:12,260 And by artifacts, we mean any kind of unwanted visual side effect 4 00:00:12,260 --> 00:00:14,680 that appears on the screen when you're trying to play a game. 5 00:00:15,180 --> 00:00:18,220 Today, we're going to talk about the common artifacts you could expect, 6 00:00:18,600 --> 00:00:22,300 what exactly causes them, and how you can try to stop them from happening. 7 00:00:22,520 --> 00:00:26,660 First up is a relatively typical one that some folks refer to as shimmering or flickering. 8 00:00:26,660 --> 00:00:30,660 That might sound a little vague, but we're talking about how some textures 9 00:00:30,660 --> 00:00:32,880 appear to be moving off and off in the distance, 10 00:00:33,560 --> 00:00:36,660 similar to how the sunlight reflects off of a pond in real life. 11 00:00:37,260 --> 00:00:40,480 It's annoying for sure, but the good news is that it doesn't typically mean 12 00:00:40,480 --> 00:00:43,080 that there's some kind of defect with your card or the game. 13 00:00:43,940 --> 00:00:46,800 Instead, shimmering is usually a form of aliasing, 14 00:00:47,380 --> 00:00:50,400 the same effect that can result in jaggies along sharp edges. 15 00:00:50,780 --> 00:00:54,460 Try fixing it by either turning down any in-game settings related to image sharpening, 16 00:00:54,460 --> 00:00:56,540 or try different anti-aliasing modes. 17 00:00:57,200 --> 00:01:01,780 Temporal anti-aliasing, or TAA, is designed partially to eliminate exactly this problem, 18 00:01:01,940 --> 00:01:03,120 so give that a shot first. 19 00:01:03,640 --> 00:01:09,240 But keep in mind that older implementations of TAA can ironically make the problem worse in some games. 20 00:01:10,000 --> 00:01:12,280 In that case, more powerful anti-aliasing methods, 21 00:01:12,380 --> 00:01:16,260 such as supersampling anti-aliasing and multisample anti-aliasing, can help. 22 00:01:16,820 --> 00:01:19,600 But those do require more computational power, 23 00:01:19,760 --> 00:01:23,640 so try out different AA modes until you find the right fit for your situation. 24 00:01:23,640 --> 00:01:25,720 Not every game has the same implementation. 25 00:01:26,260 --> 00:01:26,640 Next... 26 00:01:26,660 --> 00:01:29,740 We'll talk about one that's frustrating for DLSS users, 27 00:01:29,740 --> 00:01:32,360 especially because it's such a ballyhooed piece of tech. 28 00:01:32,860 --> 00:01:34,220 Yeah, we really used that word. 29 00:01:34,840 --> 00:01:38,900 Although DLSS brings out finer details without taxing your card too much, 30 00:01:39,240 --> 00:01:42,240 it unfortunately has a reputation for causing ghosting. 31 00:01:42,740 --> 00:01:48,620 You see, the whole way DLSS works is to compare visuals in a specific game to an ideal image, 32 00:01:48,940 --> 00:01:53,700 and then use machine learning to try and get your GPU to output a similar-looking image in-game. 33 00:01:54,240 --> 00:01:56,460 And while it works quite well in many ways, 34 00:01:56,460 --> 00:01:59,380 it also has a limitation in that it works better at higher resolutions, 35 00:01:59,600 --> 00:02:04,000 since the AI model that underpins DLSS is trained with higher-res images. 36 00:02:04,540 --> 00:02:06,700 Gaming at lower resolutions can throw off the AI, 37 00:02:06,900 --> 00:02:10,240 resulting in the ghosting and smearing that folks have come to complain about. 38 00:02:10,500 --> 00:02:14,200 Especially if you're already experiencing the shimmering artifacts we mentioned before. 39 00:02:14,420 --> 00:02:18,520 Fortunately, newer versions of DLSS have reportedly improved the situation markedly. 40 00:02:19,100 --> 00:02:21,480 But games have to add support for it, 41 00:02:21,480 --> 00:02:24,940 so there's not much you can do except wait for the more recent versions of DLSS 42 00:02:24,940 --> 00:02:26,440 to start appearing in the titles you play. 43 00:02:26,460 --> 00:02:30,380 DLSS swapper might get you somewhere, but it's not guaranteed. 44 00:02:31,040 --> 00:02:36,660 Unfortunately though, there are other artifacts that typically indicate something is wrong in one way or another. 45 00:02:37,160 --> 00:02:41,280 And I'm not talking about things like screen tearing, where the GPU is rendering things correctly, 46 00:02:41,280 --> 00:02:45,380 but the output just needs to be fixed by enabling V-Sync or variable refresh rate. 47 00:02:45,580 --> 00:02:51,680 Artifacts that are a sign of a real problem often take the form of objects like weird-colored dots, 48 00:02:51,960 --> 00:02:55,880 lines, or strange geometric shapes creeping across the screen, 49 00:02:55,880 --> 00:02:58,380 as well as textures that are straight-up missing. 50 00:02:58,980 --> 00:03:03,100 Sometimes these can be caused by just one title that isn't playing properly with your hardware. 51 00:03:03,420 --> 00:03:08,680 But if you're seeing this happen across multiple games, or even when you're not gaming at all, 52 00:03:08,940 --> 00:03:12,860 a good first course of action is to make sure your graphics card drivers are up-to-date, 53 00:03:12,860 --> 00:03:18,240 and also to return your graphics card settings to their defaults if you've overclocked the GPU itself or its VRAM, 54 00:03:18,240 --> 00:03:20,300 which is often the culprit behind problems like these. 55 00:03:21,000 --> 00:03:24,620 But let's say you've done this, and the problems are continuing. 56 00:03:24,620 --> 00:03:25,240 But let's say you've done this, and the problems are continuing. 57 00:03:25,240 --> 00:03:25,770 But let's say you've done this, and the problems are continuing. 58 00:03:25,770 --> 00:03:27,790 However, this is a good time to check the card itself. 59 00:03:27,950 --> 00:03:32,850 Make sure it's seated properly in the slot and have a look at your connectors and cables to see if something's amiss. 60 00:03:33,350 --> 00:03:36,490 Also, since overheating is a main cause of weird artifacts, 61 00:03:36,490 --> 00:03:40,730 blow out any dust from both the slot and the card itself and ensure you don't have any dead fans. 62 00:03:40,730 --> 00:03:44,390 If everything is looks all right and you're still having problems, try the card in a different PC. 63 00:03:44,390 --> 00:03:48,450 Especially as bad main system RAM can cause some of these same issues. 64 00:03:48,610 --> 00:03:51,910 You should also try updating the card's firmware, but if that doesn't help, 65 00:03:52,290 --> 00:03:55,310 you might unfortunately have a dying GPU on your hands. 66 00:03:55,310 --> 00:03:58,870 And I don't envy anyone who has to buy a new GPU 67 00:03:58,870 --> 00:04:00,110 in this economy. 68 00:04:00,490 --> 00:04:02,250 Thanks to Ugreen for sponsoring today's video. 69 00:04:02,630 --> 00:04:04,910 Ugreen is taking their earbuds to the next level 70 00:04:04,910 --> 00:04:07,410 with their new HiTune X6 ANC earbuds. 71 00:04:07,810 --> 00:04:09,710 The X6's dual active noise canceling 72 00:04:09,710 --> 00:04:11,750 offers up to 35 decibels of noise reduction 73 00:04:11,750 --> 00:04:13,950 on top of the natural passive noise production 74 00:04:13,950 --> 00:04:15,190 that you get from these earphones, 75 00:04:15,490 --> 00:04:16,990 which is perfect for a noisy commute. 76 00:04:17,190 --> 00:04:19,470 They also feature a new dynamic 10 millimeter driver 77 00:04:19,470 --> 00:04:21,510 with a diamond-like carbon moving coil. 78 00:04:21,930 --> 00:04:23,910 A refined design that's smaller and lighter 79 00:04:23,910 --> 00:04:25,890 with better ergonomics based on customer feedback 80 00:04:25,890 --> 00:04:28,490 and six microphones for clearer call quality 81 00:04:28,490 --> 00:04:31,650 that filters out up to 90% of background noise during calls. 82 00:04:32,050 --> 00:04:32,890 Upgrade your commute 83 00:04:32,890 --> 00:04:35,210 with the Ugreen HiTune X6 earbuds today 84 00:04:35,210 --> 00:04:36,650 using the link in the
